June 27th, 2014

Emergency airworthiness directive (AD) 2014-12-52 is sent to owners and operators of Honeywell International Inc. (Type Certificate previously held by AlliedSignal Inc., Garrett Turbine Engine Company) TFE731-4, -4R, -5AR, -5BR, -5R, -20R, -20AR, -20BR, -40, -40AR, -40R, -40BR, -50R, and -60 turbofan engines. This emergency AD was prompted by reports of 2nd stage low-pressure turbine (LPT2) blade separations. Analysis indicates the presence of casting anomalies at or near the root of the LPT2 blade. This condition, if not corrected, could result in LPT2 blade failure, multiple engine in-flight shutdowns, and damage to the airplane. pdf icon 2014-12-52_Emergency.pdf


AD on Rotorcraft Tailboom for Eurocopter AS350 and AS355 Helicopters

June 27th, 2014

The FAA is publishing a new airworthiness directive 2014-07-52 (AD) for certain Airbus Helicopters (previously Eurocopter France) Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, AS350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters, which was sent previously to all known U.S. owners and operators of these helicopters. This AD requires repetitively inspecting certain reinforcement angles of the rear structure to tailboom junction frame (reinforcement angles) for a crack, and repairing any cracked reinforcement angle. This AD is prompted by a report that cracks were found in the reinforcement angles on several AS355 helicopters. These actions are intended to detect a crack in the reinforcement angle, which if not corrected, could result in loss of the tailboom and subsequent loss of control of the helicopter. DATES: This AD becomes effective June 25, 2014 to all persons except those persons to whom it was made immediately effective by Emergency AD (EAD) 2014-07-52, issued on March 28, 2014, which contained the requirements of this AD. pdf icon 2014-07-52.pdf
