AD Proposed for MD Helicopters 369 and 500 Tail Rotor Pedal Support Brackets
The FAA has proposed adopting a new Airworthiness Directive (AD) for certain MD Helicopters Model 369 and 500 helicopters. This proposed AD was prompted by multiple reports of cracked magnesium cast tail rotor (T/R) pedal support brackets.
The proposed AD would require repetitively inspecting magnesium cast T/R pedal support brackets having P/N 369A7505-7, 369A7505-8, 369A7505-14, or 369A7505-15, and aluminum cast T/R pedal support brackets having P/N 369N2640-1 or 369N2640-2. If cracks or corrosion are found, replacement with an applicable aluminum cast T/R pedal support bracket would be required. This proposed AD would also prohibit installing magnesium cast T/R pedal support brackets on any helicopter.
Comments are due October 15th. You can find the proposed AD here.
