Airworthiness Directive 2017-03963
one-timeAirworthiness Directives; Airbus Helicopters Deutschland GmbH (Airbus Helicopters) (Previously Eurocopter Deutschland GmbH)
What this AD requires
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model BO-105C, BO-105LS A-3, and BO-105S helicopters. This AD requires inspecting each main rotor blade (MRB) for debonding, and is prompted by a report of incorrect bonding of the shell to the MRB. These actions are intended to detect and prevent an unsafe condition on these products.
Which aircraft AD 2017-03963 applies to
Applies only to main rotor blades (MRB) with less than 200 hours time-in-service since the MRB erosion protective shell was last replaced, where the shell was last replaced between December 1, 2010 and February 28, 2015, inclusive, or where the most recent replacement date is unknown.
Whether AD 2017-03963 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
