Airworthiness Directives; Various Aircraft Equipped With Honeywell Primus II RNZ-850( )/-851( ) Integrated Navigation Units
DATES: This AD becomes effective December 1, 2006.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of December 1, 2006.
The FAA is superseding an existing airworthiness directive (AD), which applies to various aircraft equipped with certain Honeywell Primus II RNZ850( )/851( ) integrated navigation units (INUs). That AD, as one alternative for compliance, provides for a onetime inspection to determine whether a certain modification has been installed on the Honeywell Primus II NV850 navigation receiver module (NRM), which is part of the INU. In lieu of accomplishing this inspection, and for aircraft found to have an affected NRM, the existing AD provides for revising the aircraft flight manual to include new limitations for instrument landing system approaches. This new AD requires inspecting to determine whether certain modifications have been done on the NRM; and doing related investigative, corrective, and other specified actions, as applicable; as well as further modifications to address additional anomalies. This AD results from reports indicating that erroneous glideslope indications have occurred on certain aircraft equipped with the subject INUs. We are issuing this AD to ensure that the flightcrew has an accurate glideslope deviation indication. An erroneous glideslope deviation indication could lead to the aircraft making an approach off the glideslope, which could result in impact with an obstacle or terrain.
Various Aircraft Equipped With Honeywell Primus II integrated navigation units,
Examining the Docket
You may examine the airworthiness directive (AD) docket on the Internet at http://dms.dot.gov or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 6475227) is located on the plaza level of the Nassif Building at the street address stated in the ADDRESSES section. Discussion
The FAA issued a supplemental notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that supersedes AD 20030406, amendment 3913054 (68 FR 8539, February 24, 2003). The existing AD applies to various aircraft equipped with certain Honeywell Primus II RNZ850/851 integrated navigation units (INUs). That supplemental NPRM was published in the Federal Register on May 18, 2006 (71 FR 28827). That supplemental NPRM proposed to continue to require inspecting to determine whether certain modifications have been done on the NRM; and doing related investigative, corrective, and other specified actions, as applicable; as well as further modifications to address additional anomalies.
We provided the public the opportunity to participate in the development of this AD. We have considered the comments received from the single commenter.
Request To Clarify Reply to Comment to Original NPRM
The commenter, Air Wisconsin, has requested an explanation of our reply to its comment to the original NPRM. The original comment requested clarification of the proposed requirements for inspecting to determine the modification level of the NRM and proposed that paragraph (k) of the original NPRM be revised to state that paragraph (j) of the AD need not be performed under certain conditions. The commenter asserts that our reply to that original comment was contradictory and confusing because we stated that we had made no change to paragraph (k) of the original NPRM when, in fact, paragraph (k) of the supplemental NPRM had been changed.
We acknowledge the commenter's concern. As stated in our original reply, we determined that paragraph (j) of the AD is required regardless of compliance time or the findings of paragraph (f); this is because paragraph (j) requires inspecting for Mod N, P, R, or T, as well as Mod L. Therefore, we did not change paragraph (k) of the original NPRM as the commenter suggested. However, we determined that paragraph (k) was incorrect in that it stated that paragraph (f) did not need to be done if paragraph (j) was accomplished within the compliance time specified by paragraph (f). Paragraph (f) of the AD deals with compliance times and has no findings, while paragraph (g) of the AD requires an inspection and has findings. Therefore, it was our intent to revise paragraph (k) to read as it appears in the supplemental NPRM; that is, if paragraph (j) is accomplished within the compliance time specified by paragraph (f), paragraph (g) does not need to be done. We have made no further changes to paragraph (k) of the AD in this regard.
Explanation of Change To Applicability
We have revised the applicability of the AD to identify model designations as published in the most recent type certificate data sheet for the affected models.
Clarification of INU References
The applicability of the supplemental NPRM specifies that the AD
applies to aircraft ``equipped with a Honeywell Primus II RNZ850/851
INU having a part number identified in Table 1 of this AD.'' However,
the Honeywell service bulletins identified in the following table
variously refer to ``850/851,'' ``850/A/B/C,'' ``851/A/B/C,'' and
``850(X)/851(X)'' INUs, indicating that the RNZ850/851 part number
might or might not contain a suffix letter. Although the service
bulletins identified in the following table make it clear that the INU
part numbers, as identified in Table 1 of the AD, are the primary
identifiers of all affected INUs, we have determined that these various
suffix references could cause confusion. Therefore, to address all references to suffix letters in the service bulletins, we
have revised the AD to read ``850( )/851( )'' where applicable. Honeywell Service Information

We have carefully reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance
For the purposes of this AD, we estimate that there are 3,063 aircraft worldwide that may be equipped with a part that is subject to this AD, including about 1,500 aircraft of U.S. registry.
The inspection to determine whether Mod L has been done, which is currently required by AD 20030406 and retained in this AD, will take about 1 work hour per aircraft, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the currently required actions is $80 per aircraft.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, ``General requirements.'' Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.
We have determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive Order 12866;
(2) Is not a ``significant rule'' under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
(3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation. List of Subjects in 14 CFR Part 39

Note 1: This AD applies to Honeywell Primus II RNZ850( )/851(
) INUs installed on any aircraft, regardless of whether the aircraft
has been otherwise modified, altered, or repaired in the area
subject to the requirements of this AD. For aircraft that have been
modified, altered, or repaired so that the performance of the
requirements of this AD is affected, the owner/operator must request
approval for an alternative method of compliance in accordance with
paragraph (m) of this AD. The request should include an assessment of the effect of the
modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
(d) This AD results from reports indicating that erroneous glideslope indications have occurred on certain aircraft equipped with the subject INUs. We are issuing this AD to ensure that the flightcrew has an accurate glideslope deviation indication. An erroneous glideslope deviation indication could lead to the aircraft making an approach off the glideslope, which could result in impact with an obstacle or terrain.
(e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Requirements of AD 20030406
Compliance Time For Action
(f) Within 5 days after March 11, 2003 (the effective date of AD 20030406), accomplish the requirements of either paragraph (g) or (h) of this AD. After the effective date of this AD, only
accomplishing the requirements of paragraph (g) of this AD is acceptable for compliance with this paragraph.
Inspection To Determine Part Number
(g) Perform a onetime general visual inspection of the modification plate for the Honeywell Primus II NV850 Navigation Receiver Module (NRM); part number 7510134811, 831, 901, or 931; which is part of the Honeywell Primus II RNZ850( )/851( ) INU; to determine if Mod L has been installed. The modification plate is located on the bottom of the Honeywell Primus II RNZ850( )/851( ) INU, is labeled NV850, and contains the part number and serial number for the Honeywell Primus II NV850 NRM. If Mod L is
installed, the letter L will be blacked out. Honeywell Alert Service Bulletin 751010034A0035, dated July 11, 2003, is an acceptable source of service information for the inspection required by this paragraph.
(1) If Mod L is installed, before further flight, do paragraph (h) or (j) of this AD. After the effective date of this AD, only accomplishment of paragraph (j) is acceptable for compliance with this paragraph.
(2) If Mod L is not installed, no further action is required by this paragraph.
Note 2: For the purposes of this AD, a general visual inspection is defined as: ``A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to enhance visual access to all exposed surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.''
Note 3: For more information on the inspection specified in
paragraph (g) of this AD, refer to Honeywell Technical Newsletter A233850001, Revision 1, dated January 21, 2003.
Aircraft Flight Manual (AFM) Revision
(h) Revise the Limitations section of the AFM to include the following statements (which may be accomplished by inserting a copy of the AD into the AFM):
When crossing the Outer Marker on glideslope, the altitude must be verified with the value on the published procedure.
For aircraft with a single operating glideslope receiver, the approach may be flown using normal procedures no lower than Localizer Only Minimum Descent Altitude (MDA).
For aircraft with two operating glideslope receivers, the
aircraft may be flown to the published minimums for the approach
using normal procedures if both glideslope receivers are tuned to
the approach and both crew members are monitoring the approach using independent data and displays.''
(i) As of March 11, 2003, no person may install a Honeywell Primus II NV850 NRM on which Mod L has been installed, on the Honeywell Primus II RNZ850( )/851( ) INU of any aircraft, unless paragraph (h) or (k) of this AD is accomplished. As of the effective date of this AD, only accomplishment of paragraph (k) is acceptable for compliance with this paragraph.
New Requirements of This AD
Inspection To Determine Modification Level of NRM
(j) For aircraft on which Mod L was found to be installed during the inspection required by paragraph (g) of this AD, or for aircraft on which paragraph (h) of this AD was accomplished: Within 24 months after the effective date of this AD, do an inspection of the modification plate on the Honeywell Primus II NV850 NRM; part number 7510134811, 831, 901, or 931; which is part of the
Honeywell Primus II RNZ850( )/851( ) INU; to determine if Mod L, N, P, R or T is installed. The modification plate located on the bottom of the Honeywell Primus II RNZ850( )/851( ) INU is labeled NV850, and contains the part number and serial number for the Honeywell Primus II NV850 NRM. If Mod L, N, P, R or T is installed, the corresponding letter on the modification plate will be blacked out.
