EASA AD 2019-0255
SUPERSEDED BY EASA AD 2020-0094
Summary
EASA Airworthiness Directive 2019-0255 is an airworthiness directive issued for Airbus Helicopters EC175 B helicopters. It mandates repetitive inspections of the locking mechanisms on both right-hand and left-hand cargo doors to ensure proper operation and prevent potential in-flight cargo door loss. The directive applies to all serial numbers of the EC175 B model.
What Changed
This directive introduces mandatory repetitive inspections of the cargo door locking mechanisms on EC175 B helicopters following a reported incident where a cargo door handle was found open and the locking mechanism inoperative. It requires corrective actions if any deficiencies are found during inspections. This AD is an interim measure and may be followed by further actions.
Why It Matters
This directive is critical for aviation professionals as it addresses a safety risk that could lead to loss of a cargo door in flight, potentially causing damage or reduced helicopter control. Operators and maintenance teams must ensure compliance to maintain aircraft airworthiness and safety. Failure to comply could result in unsafe flight conditions and regulatory penalties.
What To Do
Operators of EC175 B helicopters must inspect the locking mechanisms of both cargo doors within specified flight hour limits—before exceeding 440 flight hours if under 330 flight hours accumulated, or within 110 flight hours after the effective date if 330 or more flight hours are accumulated. Inspections must then be repeated every 440 flight hours. Any detected deficiencies must be corrected before the next flight.
