CASA has automatically adopted the European Aviation Safety Agency’s (EASA) latest emergency airworthiness directive relating to the Airbus Helicopters H2225 (formerly Eurocopter EC225), of the type that crashed in Norway last week.

Emergency Airworthiness Directive 2016-0089-E requires H225 operators to do four things before the aircraft’s next flight.

  1. Check the correct installation of the front and right hand and left hand rear main gearbox suspension bars in accordance with the instructions of Airbus Helicopters (AH) EC225 Alert Service Bulletin No.53A058.
  2. Check the chip detectors of the main gearbox for absence of metallic particles in accordance with the instructions of Work Card 60.00.00.212 of AH EC225 Maintenance Manual (MMA).
  3. Perform an oil filter check of the main gearbox for absence of metallic particles, in accordance with the instructions of Work Card 63.24.01.061 of AH EC 225 MMA and, if any particle is collected, refer to Standard Practices Manual MTC 20.08.02.601.
  4. For helicopters equipped with M’ARMS vibration health monitoring system, download data and check for any threshold exceedance. Ensure availability of these data in case future analysis needed.

Australian H225 operators must comply with the provisions of the directive before any further flights of the aircraft (apart from one positioning flight to a repair place, if needed). It can be found on the CASA website and the EASA website.

The crash last Friday killed all 13 on board an H225 that was returning from an offshore oil platform. The helicopter’s main rotor detached in flight and was videoed by a witness on the ground as it spun down to earth.
