What to do
Operators of affected Robinson helicopter models must begin visually inspecting the specified TRB tip caps for corrosion starting April 2, 2024, and continue repetitive inspections as required. Corrosion must be removed if detected, and all affected TRBs must be removed from service within 10 months of the effective date. Pilots holding at least a private pilot certificate may perform the visual checks, but mechanics must conduct detailed inspections and maintenance actions. Compliance must be recorded in maintenance logs per FAA regulations.
Summary
The Federal Aviation Administration Airworthiness Directive 2024-04-02 is a final rule addressing certain Robinson Helicopter Company Model R22, R22 Alpha, R22 Beta, R22 Mariner, R44, R44 II, and R66 helicopters. It focuses on inspecting tail rotor blade (TRB) tip caps with specific part and serial numbers for corrosion and requires removal of affected TRBs from service to prevent unsafe conditions.
What changed
This new airworthiness directive introduces mandatory repetitive visual inspections of specified TRB tip caps for corrosion and requires removal of corrosion when found. It also mandates removing all affected TRBs from service within 10 months and prohibits their installation on any helicopter. The AD differs from related service bulletins by requiring mechanic inspections and a shorter compliance timeline for TRB removal.
Why it matters
This AD is critical for aviation professionals because corrosion-related failure of TRB tip caps can cause severe vibrations and potential loss of tail rotor gearbox integrity, leading to reduced helicopter controllability and possible accidents. Operators and maintenance teams must ensure compliance to maintain flight safety and avoid costly in-service failures. The directive also clarifies inspection responsibilities and timelines, impacting maintenance planning and recordkeeping.
