Check the bullet seal inflation per instructions described in AS 332 Alert SB No. 30.00.52 original issue or later DGAC / EASA approved revisions.

4. As a result of the bullet seal inflation check per Requirement 3, if the pressure read on the pressure gage is equal to or more than 3 bars (RH and LH sides), the pipes meet the requirements and no action is necessary before resuming flights.5. As a result of the bullet seal inflation check per Requirement 3, if the pressure read on the pressure gage is less than 3 bars on one of the 2 sides, replace the pipe(s) that does (do) not meet the requirements, as per instructions of the Alert SB 30.00.52 original issue or later DGAC / EASA approved revisions.Note: French DGAC Airworthiness Directive (AD) F-2002-257-080 R1, approved under EASA reference number 2005-1916 dated 22 February 2005 refers.

Compliance:	1. On the next engine removal after the effective date of this AD but not later than 550 flight hours or 24 months after the effective date of this AD, whichever comes first.2. With in 10 days after the effective date of this AD but before performing any flight in the conditions defined above.3. On the next engines removal after the effective date of the AD but not later than 550 flight hours or 24 months after the effective date of this AD or before performing any flight in the conditions defined above, whichever comes first.4. No action required.5. Before further flight.
	This Airworthiness Directive becomes effective on 7 July 2005.
Background:	There have been reports of non-compliant P2 pipes, which might cause insufficient inflation of the bullet seal and lead to engine flame-out during flights in icing conditions.The actions specified in this Airworthiness Directive address the risk associated with non-compliant pipes and resultant engine flame-outs.
