Flight Trails Helicopter, MD Helicopters, Inc. Appliances
This AD applies to Flight Trails Helicopter, MD Helicopters, Inc. Hardpoint Assemblies, 369D, 369E, 369F, 369FF, 500N.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to Flight Trails Helicopters, Inc. hardpoint assemblies, installed in accordance with Supplemental Type Certificate (STC) No. SH6080NM, or in accordance with Federal Aviation Administration (FAA) Form 337, "Major Repair and Alteration," approved on McDonnell Douglas Helicopter Systems (MDHS) Model 369D, 369E, 369F, 369FF, and 500N helicopters, that requires removing any Flight Trails Helicopters, Inc. hardpoint assembly not identified by part number (P/N) and serial number (S/N). This amendment is prompted by two incidents in which the hardpoint assembly used to support a search light or night vision system reportedly failed. The actions specified by this AD are intended to prevent failure of the hardpoint assembly, separation of the hardpoint assembly from the helicopter, and subsequent contact between the hardpoint assembly and the fuselage or rotor system of the helicopter.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
