2002-13-06: This amendment adopts a new airworthiness directive (AD) for Eurocopter Deutschland GmbH (ECD) (Eurocopter) Model BO-105A, BO-105C, BO-105 C-2, BO-105 CB-2, BO-105 CB-4, BO-105S, BO-105 CS-2, BO-105 CBS-2, BO-105 CBS-4, and BO-105LS A-1 helicopters. This action requires creating a component log card or equivalent record and determining the calendar age, number of flights, and flight hours time-in-service (TIS) on two part-numbered tension-torsion (T-T) straps; inspecting and replacing certain T-T straps, as necessary; and modifying certain main rotor heads if alternate T-T straps are installed. This action also establishes an additional life limit for these two part-numbered T-T straps. This amendment is prompted by an accident in which a main rotor blade separated from a Eurocopter Model MBB-BK 117 helicopter due to fatigue failure of a T-T strap. The same part-numbered T-T strap is used on Eurocopter Model BO-105 helicopters. That accident indicated a need to establish an additional life limit for certain part-numbered T-T straps. The actions specified in this AD are intended to prevent fatigue failure of a T-T strap, loss of a main rotor blade, and subsequent loss of control of the helicopter.

2002-13-05: This amendment adopts a new airworthiness directive (AD) for specified MD Helicopters, Inc. (MDHI) helicopters with a tailboom modified according to Aerometals Supplemental Type Certificate (STC) SH5055NM or SH4801NM. This AD requires an inspection to identify the part number (P/N) of the bolts that attach the tail rotor gearbox to the tailboom and replacing any bolt of inadequate grip length with an airworthy bolt. This AD also requires determining the number of bolt threads protruding from each nutplate and adding an additional washer if more than four threads protrude. This amendment is prompted by the discovery that bolts of inadequate grip length were specified to attach the tail rotor gearbox to the tailboom. The actions specified by this AD are intended to prevent loss of a tail rotor gearbox due to attaching bolts of inadequate grip length and subsequent loss of control of the helicopter.

2002-12-02: This amendment adopts a new airworthiness directive (AD) for Eurocopter France (ECF) Model AS332L2 helicopters. This action requires visually inspecting the engine compartment fire extinguisher bottle (bottle) for correct placement and installation of the percussion heads and attachment cartridges and if, incorrectly installed, making the necessary corrections. This action also requires marking the bottle's indicating label with "Amendment A" after making the necessary corrections. This amendment is prompted by the discovery that some of the spare bottles have interchanged percussion heads. The actions specified in this AD are intended to prevent release of the fire-extinguishing agent into the wrong engine compartment, failure to extinguish a fire, and subsequent loss of control of the helicopter.

2002-11-09: This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) \nModel 407 helicopters that requires visually inspecting the forward hanger bearing bracket (bracket) for a crack. This amendment is prompted by reports of cracks in the bracket. The actions specified by this AD are intended to detect a crack in the bracket, to prevent loss of tail rotor drive or control and subsequent loss of control of the helicopter.
|
2002-12-01: This amendment adopts a new airworthiness directive (AD), applicable to certain BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes, that requires a functional test of the shortening mechanism of the nose landing gear for free movement of the capsule in the upper and lower bearings, and corrective action, if necessary. This action is necessary to prevent damage to the capsule, which could result in inability to extend the nose landing gear in normal or emergency situations, and consequent injury to passengers and flight crew. This action is intended to address the identified unsafe condition.
|
2002-11-08: This amendment adopts a new airworthiness directive (AD) that is applicable to Rolls-Royce plc (RR) RB211 Trent 875, 877, 884, 892, 892B, and 895 series turbofan engines with certain part number (P/N) low pressure compressor (LPC) fan blades installed. This action requires initial and repetitive ultrasonic inspection of the fan blade dovetail roots. This amendment is prompted by the loss of an LPC fan blade during takeoff. The actions specified in this AD are intended to prevent multiple LPC fan blade failures due to cracks, which could result in uncontained engine failure and possible damage to the airplane.
|
2002-11-02: This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Model 390 airplanes. This AD requires you to insert a temporary change into the FAA-approved Airplane Flight Manual (AFM) that adds a limitation for prohibiting flight into icing conditions and adds procedures for when an icing condition occurs. This AD is the result of reports of a manufacturing problem with the wing leading edge anti-ice system. The actions specified by this AD are intended to minimize the potential hazards associated with operating these airplanes in icing conditions by providing procedures and limitations associated with such conditions.
|
2002-10-09: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Gulfstream Aerospace LP Model Galaxy and Gulfstream 200 airplanes. This action requires repetitive inspections for evidence of fuel accumulation inside of the aft service compartment; and follow-on actions, if necessary. This AD also provides for an optional terminating modification. This action is necessary to prevent such fuel accumulation, which could result in fuel vapors coming into contact with ignition sources and consequent fire. This action is intended to address the identified unsafe condition.
|
2002-10-04: This amendment adopts a new airworthiness directive (AD) that is applicable to General Electric Company (GE) CF6-80E1A2 turbofan engines. This action requires replacing a certain low pressure turbine rotor (LPTR) shaft at or before reaching a new reduced life cycle limit. This amendment is prompted by an updated low cycle fatigue (LCF) analysis of the LPTR shaft. The actions specified in this AD are intended to prevent LCF cracking and failure of the LPTR shaft due to exceeding the life limit, which could result in an uncontained engine failure and damage to the airplane.

2002-09-11: This amendment supersedes Airworthiness Directive (AD) 2001-05-03, which applies to certain SOCATA-Groupe AEROSPATIALE (Socata) Model TBM 700 airplanes. AD 2001-05-03 currently requires you to apply Loctite on attaching bolt/screw threads of inboard, central, and outboard carriages; increase tightening torques of associated hardware; and replace central carriage attaching bolts. The French airworthiness authority has determined that certain service information referenced in AD 2001-05-03 be removed and additional inspection of the flap carriage attaching bolts, screws, and barrel nut be included. Therefore, this AD will retain the requirements of the current AD and will add the information communicated by the French airworthiness authority. The actions specified by this AD are intended to prevent the flap attaching bolts/screws from becoming loose and separating from the airplane, which could cause rough or irregular control. Such rough or irregular control could lead to the loss of control of the airplane.
