2002-14-03: This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-11 and 11F airplanes. This action requires a one-time inspection to detect loose preload-indicating (PLI) washers or cracked or corroded nuts of the lower bolts of the inboard flap outboard hinge, and replacement with new parts if necessary. This action is necessary to detect and correct loose PLI washers or cracked or corroded nuts of the lower bolts of the inboard flap outboard hinge, which could result in separation of the inboard flap outboard hinge from the wing structure and consequent reduced controllability of the airplane.
2002-14-20: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 737-600, -700, -800, and -900 series airplanes. This action requires measuring the electrical voltage at the circuit breaker for a certain pitot heater to determine if the pitot heater is connected to the correct power supply bus, and performing corrective action, if necessary. This action is necessary to prevent ice from blocking the pitot tube that provides airspeed data to the captain. Such ice blockage could lead to the flightcrew receiving incorrect airspeed data, which could result in loss of control of the airplane if the flightcrew fails to recognize that the data are incorrect. This action is intended to address the identified unsafe condition.
2002-14-16: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model 717-200 airplanes, that requires repetitive inspections for cracking of the spoiler hold-down actuator supports located on the left and right wing rear spars; adjustment of the spoiler hold-down actuators; and replacement of cracked spoiler hold-down actuator supports with new, improved supports. This AD also requires replacement of all spoiler hold-down actuator supports with new, improved supports, which terminates the repetitive inspections. The actions specified by this AD are intended to detect and correct as well as to prevent cracks in the spoiler hold-down actuator supports, which could lead to reduced spoiler hold-down capability, resulting in loss of the back-up protection of the spoiler float hold-down and unavailability of monitoring for an uncommanded spoiler movement.
2002-13-11: This amendment adopts a new airworthiness directive (AD) for specified Eurocopter France (ECF) model helicopters that requires installing front and side covers to protect the yaw control. This amendment is prompted by a report of a mobile phone falling between the windshield canopy (canopy) and the cabin floor jamming the yaw control pedal. The actions specified by this AD are intended to prevent an object from sliding between the canopy and the cabin floor, loss of yaw control, and subsequent loss of control of the helicopter.
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.
