Plain English Summary

1/10 complexity

What this does: This is an Airworthiness Directive (a mandatory safety order) requiring owners and operators of specific Hughes 369D helicopters to replace the main rotor pitch control rod.

Who it affects: Owners and operators of McDonnell Douglas (Hughes) 369D helicopters with serial numbers 0001D through 0043D.

What you must do: Replace the main rotor pitch control rod within 100 hours of flight time after 30 November 1977, following the instructions in Hughes Service Information Notice DN-6.

Why it matters: The main rotor pitch control rod is a critical component that allows the pilot to control the angle (pitch) of the helicopter's main rotor blades. A failure of this part would cause immediate loss of control and likely result in a crash. This directive addresses a known safety defect in early production aircraft.
