1 PROPOSED RULES: Boeing Model 737–300, and 747–400 Series Airplanes, et al.,
This document revises an earlier supplemental notice of proposed

rulemaking (NPRM), applicable to certain Boeing Model 737300, 400,
500, 600, 700, 700C, 800, and 900, and 747400 series airplanes;
and Model 757, 767, and 777 airplanes. The first supplemental NPRM
would have required modifying the static inverter by replacing resistor
2 RULES: ATR Model ATR72 Airplanes,
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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:
Incomplete
3 RULES: Airworthiness Directives
The FAA is superseding an existing airworthiness directive (AD) for PW JT9D7R4 series turbofan engines. That AD currently requires removing certain reduced cooling flow 2nd stage highpressure turbine (HPT) vane assemblies installed in certain 2nd stage HPT vane cluster assemblies. It also requires a visual and a fluorescent penetrant inspection
4 RULES: Cessna Aircraft Co. Models 401, 401A, 401B, 402, 402A, and 402B Airplanes,
The FAA is adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Models 401, 401A, 401B, 402, 402A, and 402B airplanes. This AD requires an inspection of the auxiliary wing spar near the location where the main landing gear trunnion is mounted for cracks; immediate replacement if cracks of 0.5 inch or more are found;
5 RULES: Bombardier Model DHC–8–102, et al.; Airplanes Equipped with a
This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 20082603. This AD requires modifying the electronic strike system of the cockpit door. This AD results from a report indicating that the equipment is defective. We are issuing this AD to prevent failure of this equipment, which could compromise
6 RULES: Boeing Model 737–300, –400, and –500 Series Airplanes Equipped
We are adopting a new airworthiness directive (AD) for certain Boeing Model 737300, 400, and 500 series airplanes. This AD requires revising the maintenance program to include new fuel system limitations for airplanes modified in accordance with STC ST00127BO. This AD also requires inspections and checks of the DTSDs and corrective actions, if
7 PROPOSED RULES: Rolls–Royce plc (RR) RB211–524 Series Turbofan Engines,
The FAA proposes to supersede an existing airworthiness directive (AD) for certain RR RB211524 series turbofan engines. That AD currently requires initial and repetitive borescope inspections of the head section and meterpanel assembly of the combustion liner, and replacement if necessary with serviceable parts. This proposed AD would require
8 RULES: Honeywell International Inc. ALF502L–2 and ALF502L–2C Turbofan
The FAA is adopting a new airworthiness directive (AD) for Honeywell International Inc. ALF502L2 and ALF502L2C turbofan engines with certain highpressure compressor (HPC) first stage discs installed. This AD requires performing a dimensional inspection to determine if excessive disc balance material was removed and a magnetic particle inspection
9 PROPOSED RULES: Boeing Model 747–200C and 200F Series Airplanes, et al.,
We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 747200C and 747200F series airplanes. This proposed AD would require installing larger moisture shrouds and additional drain lines in the electrical/electronic equipment center. This proposed AD results from reports of water contamination in the electrical/electronic
10 RULES: Pratt & Whitney (PW) JT9D–7 Series Turbofan Engines,
The FAA is adopting a new airworthiness directive (AD) for PW models JT9D7, 7A, 7AH, 7H, 7F, and 7J turbofan engines. This AD requires initial and repetitive borescope inspections of the 2nd stage highpressure turbine (HPT) rotor and stator assembly. This AD results from an uncontained failure of a 2nd stage HPT rotor disk that caused the engine
