Airworthiness Directive · Amendment 39-15961 · Turbomeca S.A. ARRIUS 2F Turboshaft Engines
Turbomeca S.A. ARRIUS 2F Turboshaft Engines
Superseded. A later AD replaced this one: AD 2012-07-09. Comply with the one in force.
This AD applies to Turbomeca S.A. ARRIUS 2F turboshaft engines with P3 air pipe, part number 0319719180, installed. These engines are installed on, but not limited to, Eurocopter EC120B helicopters.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions within 100 operating hours after the effective date of this AD. Use paragraphs 2.B.(1) through 2.C.(2) of Turbomeca Mandatory Service Bulletin No. 319 75 4810, dated May 14, 2008.
(1) Visually inspect P3 air pipe (first section) and RH rear half-wall.
(2) Inspect play between P3 air pipe (first section) and RH rear half-wall.
(3) Replace P3 air pipe (first section) if any damage is found.
(4) Readjust the first section of the P3 air pipe if the inspected clearance is found to be not compliant.
(5) If the play after readjusting the first section of the P3 air pipe is still less than 0.5 mm, repeat paragraphs (e)(1) through (e)(4) of this AD within intervals of 100 hours time-since-last inspection.
(6) Replace RH rear half-wall if any damage is found.
None.
