AD: Airbus Helicopters

AD NUMBER: 2017-19-21

PRODUCT: Airbus Helicopters Model EC225LP helicopters.

ACTION: Final Rule.

SUMMARY: This AD requires modifying the emergency lubrication system (EMLUB).

This AD was prompted by two incidents of emergency ditching after there was a warning of a loss of oil pressure and a false EMLUB failure.

The actions of this AD are intended to address an unsafe condition on these products.

COST: The FAA estimates this AD affects 4 helicopters of U.S. Registry and that labor costs average $85 per work-hour. Based on these estimates, we expect the following costs. The FAA estimates that 34 workhours are needed to replace the air and glycol pressure switches, modify the helicopter wiring, replace the glycol pump, and replace the MGB lubrication card. The required parts cost $121,695 per helicopter. Based on these estimates, the total costs are $124,585 per helicopter and $498,340 for the U.S. fleet.

DATES: This AD is effective October 30, 2017.
