AD NUMBER: 2004-09-22 MANUFACTURER: AvCraft Aerospace GmbH SUBJECT: Airworthiness Directive 2004-09-22 SUMMARY: This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-300 series airplanes, that requires modification of a certain ground cooling fan. This action is necessary to prevent overheating of the connecting terminals of the ground cooling fan, which could result in smoke or fire in the flight compartment and main cabin. This action is intended to address the identified unsafe condition.

AD NUMBER: 2004-10-01 MANUFACTURER: Pratt & Whitney SUBJECT: Airworthiness Directive 2004-10-01 SUMMARY: The FAA is adopting a new airworthiness directive (AD) for Pratt & Whitney (PW) JT9D-3A, -7,-7A, -7AH, -7H, -7F, -7J, -20, and -20J turbofan engines. This AD clarifies a life limit for certain part numbers of 6th stage low pressure turbine (LPT) air seals, and requires their removal from service before accumulating 15,000 cycles since-new (CSN). This AD results from reports of certain 6th stage LPT air seals possibly not being life tracked due to confusion from updates to the engine manuals. We are issuing this AD to prevent failure of the 6th stage LPT air seal, which could cause LPT damage

AD NUMBER: 2000-02-07R1 MANUFACTURER: Bombardier SUBJECT: Airworthiness Directive 2000-02-07 R1 SUMMARY: This amendment revises an existing airworthiness directive (AD), applicable to all Bombardier Model DHC-7-100 series airplanes, that currently requires repetitive high frequency eddy current inspections to detect cracks on the locking pin fittings of the baggage door and locking pin housings of the fuselage; repetitive detailed inspections to detect cracks of the inner door structure on all four door locking attachment fittings; and corrective actions if necessary. In lieu of accomplishing the corrective actions, that amendment also provides a temporary option, for certain cases, for revising the Airplane Flight Man

AD NUMBER: 2004-09-34 MANUFACTURER: General Electric SUBJECT: Airworthiness Directive 2004-09-34 SUMMARY: The FAA is superseding an existing airworthiness directive (AD) for General Electric Company (GE) CF6-80E1 model turbofan engines with high pressure turbine (HPT) stage 2 (S2) nozzle guide vanes (NGVs) part number (P/N) 1647M84G09 or 1647M84G10, installed. That AD currently requires flex borescope inspections of HPT S2 NGVs installed in CF6-80E1 model turbofan engines. This AD requires the same actions but at reduced compliance intervals. This AD results from inspection findings of HPT S2 NGVs that show cracks from distress could occur sooner and grow faster than originally predicted. We are issuing this AD to prev
