AD NUMBER: 2011-18-12
PRODUCT: Eurocopter Model AS350B, B1, B2, B3,
BA, and D; and AS355E, F, F1, F2, and N Helicopters
SUBJECT: Airworthiness Directive 2011-18-12
ACTION: Final rule; request for comments.
SUMMARY: The FAA is superseding an existing
airworthiness directive (AD) for the specified ECF model
helicopters. This AD results from a mandatory continuing
airworthiness information (MCAI) AD issued by the European Aviation
Safety Agency (EASA), which is the Technical Agent for the Member
States of the European Union.
The MCAI AD states that some cracks have been discovered in the
spar of the upper fin on Model AS355N helicopters. Due to the fin
design similarity between AS350 and AS355 helicopters, this AD
action applies to both helicopter models.
Modifying the upper and lower fin attachment is intended to
prevent failure of a spar, loss of a fin, a separated fin hitting a
rotor, and subsequent loss of control of a helicopter.
DATES: This AD becomes effective on February 8,
