Airworthiness Directives; Airbus Helicopters Federal Aviation Administration FAA, DOT.
ACTION: Notice of proposed rulemaking NPRM.
AGENCY:

The FAA proposes to supersede Airworthiness Directive AD
20190312, which applies to certain Airbus Helicopters Model EC225LP
helicopters. AD 20190312 requires repetitively inspecting, cleaning, and lubricating each life raft inflation cylinder percussion system bellcrank bellcrank. Since the FAA issued AD
20190312, the FAA determined that any affected bellcrank must be replaced with a serviceable bellcrank, which would terminate the repetitive actions.
This proposed AD would continue to require the actions specified in AD
20190312, and would require replacing any affected bellcrank with a serviceable bellcrank. The FAA is proposing this AD to address the unsafe condition on these products.
DATES: The FAA must receive comments on this proposed AD by April 12, 2021.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:
