Airworthiness Directives; Columbia Aircraft Manufacturing Models LC41-550FG and LC42-550FG Airplanes

Mon, Dec 11 2006 11:00:00 GMT

The FAA is adopting a new Airworthiness Directive (AD) for all Columbia Aircraft Manufacturing (previously The Lancair Company) Models LC41550FG and LC42550FG airplanes equipped with Kelly Aerospace Thermal Systems Supplemental Type Certificate (STC) SA02260CH, Thermawing Deice System (also known as EVade). This AD requires you to deactivate the deice system and install a placard in clear view of the pilot. This AD results from problems with the installation of the Kelly Aerospace Thermal Systems Thermawing Deice System following STC SA02260CH. We are issuing this AD to prevent a short circuit condition at the deice heater connector, which could result in damage to the wings and horizontal stabilizer. This damage could lead to reduced structural integrity of the airplane.

Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135ER and -135KE Airplanes; and

Mon, Dec 11 2006 11:00:00 GMT

The FAA is adopting a new airworthiness directive (AD) for all EMBRAER Model EMB135ER and 135KE airplanes and Model EMB145, 145ER, 145MR, 145MP, and 145EP airplanes. This AD requires inspecting the fuel quantity indication system (FQIS) wire harness and the direct current (DC) fuel pump wire harness to determine if the harnesses are properly attached at their respective attachment points and properly separated from one another, and performing corrective actions if necessary. This AD results from a report that the FQIS wire harness may not be properly attached at its attachment points or properly separated from the DC fuel pump wire harness. We are issuing this AD to prevent chafing between those harnesses or chafing of the harnesses against adjacent airplane structure or components, which could present a potential ignition source that could result in a fire or explosion.

Airworthiness Directives; Fokker Model F27 Mark 500 Airplanes

Mon, Dec 11 2006 11:00:00 GMT

The FAA is adopting a new airworthiness directive (AD) for all Fokker Model F27 Mark 500 airplanes. This AD requires an inspection to determine whether certain main landing gear (MLG) drag stay units (DSUs) are installed. This AD also requires an ultrasonic inspection to determine if certain tubes are installed in the affected DSUs of the MLG, and related investigative/corrective actions if necessary. This AD results from a report that, due to fatigue cracking from an improperly machined radius of the inner tube, a drag stay broke, and, consequently, led to the collapse of the MLG during landing. We are issuing this AD to prevent such fatigue cracking, which could result in reduced structural integrity or collapse of the MLG.

Airworthiness Directives; Bombardier Model DHC-8-102, -103, and - 106 Airplanes; and Model DHC-8-200 and DHC-8-300

Mon, Dec 11 2006 11:00:00 GMT

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model DHC8100 (as described above), DHC8200, and DHC8300 series airplanes. This proposed AD would require doing a onetime inspection for damage of the electrical cable harness assembly located on the left and right wing root to fuselage aft seal, and repair if necessary; and reworking the fuselage aft seal assembly (left and right) to create a clearance between the electrical cable assemblies and the edge of the fairing panel. This proposed AD results from a report that an airplane encountered an uncommanded propeller feathering during climb, which resulted in an emergency landing. We are proposing this AD to prevent chafing or grounding of the wiring against the aft seal assemblies, which, if not corrected, could interrupt the operation of various systems, including the propeller feather control, alternating current (AC) electrical power, and standby hydraulic power, and result in reduced controllability of the

Airworthiness Directives; Pacific Aerospace Corporation Ltd Model 750XL Airplanes

Mon, Dec 11 2006 11:00:00 GMT

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as possible undersize rivets in the fuselage roof at STN 180.85, BL 19.67, WL 86.2. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

Airworthiness Directives; Pilatus Aircraft Limited PC-12 and PC- 12/45 Airplanes

Mon, Dec 11 2006 11:00:00 GMT

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as executive seats equipped with pedestal legs that were produced using a material that deviates from the approved design data. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

Airworthiness Directives; Raytheon Aircraft Company (The Beech Aircraft Company and BEECH Previously Held Type

Mon, Dec 11 2006 11:00:00 GMT

We propose to supersede Airworthiness Directive (AD) 72-22-01, which applies to certain Raytheon Aircraft Company (RAC) (The Beech Aircraft Company and BEECH previously held Type Certificate Nos. 3A15, 3A16, 5A3, and A777) Models 33, 35, 36, 45, and 95 series airplanes. AD 722201 currently requires you to determine if each uplock roller is of the greasible type (one having a drilled and grooved inner race), replace any nongreasible uplock roller (one having a solid inner race) with the greasible type before further flight, install hollow zerk ended mounting bolts on the uplock rollers, and repetitively lubricate the uplock mechanism. Since we issued AD 722201, there was a recent incident involving a RAC Model 95B55B (T42A) airplane where a seizure of the uplock rollers occurred. This malfunction of the uplock rollers is addressed in AD 722201. Thus, the FAA has determined that the actions of AD 722201 should also apply to certain serial numbers of the Model 95B55B (T42A) airplanes. Consequently,

Norfolk Southern Railway Company--Adverse Abandonment--St. Joseph County, IN

Mon, Dec 11 2006 11:00:00 GMT
