Simple Flying contacted Airbus about this issue. A spokesperson responded with the following statement:
“Safran Aerosystems informed Airbus of a number of a limited batch of fuel pumps, currently fitted onto some A320 [Family jets] in-service aircraft (and in spare stock), which could be subject to a quality issue. Safety is the No. 1 priority. According to the standard process, operators have been notified and the authorities have been involved to launch the appropriate AD. No in service issues have been reported. The pumps belonging to this batch have been well identified and are subject to a dedicated remove/replacement action plan in collaboration with Safran Aerosystems. Current production standard of the A320 [Family jets] is not affected by this quality escape. Less than 2% of the fleet could potentially be affected.”
Which aircraft are affected?
EASA states that this issue affects aircraft that have a date of manufacture before June 30th, 2015. Unfortunately, this potentially covers a very wide range of A320 Family variants, as noted by EASA:
Airbus A318-111, A318-112, A318-121, A318-122, A319-111, A319-112, A319-113, A319-114, A319-115, A319-131, A319-132, A319-133, A319-151N, A319-153N, A319-171N, A320-211, A320-212, A320-214, A320-215, A320-216, A320-231, A320-232, A320-233, A320-251N, A320-252N, A320-253N, A320-271N, A320-272N, A320-273N, A321-111, A321-112, A321-131, A321-211, A321-212, A321-213, A321-231, A321-232, A321-251N, A321-251NX, A321-252N, A321-252NX, A321-253N, A321-253NX, A321-271N, A321-271NX, A321-272N and A321-272NX aircraft.
While all manufacturer serial numbers of these aircraft types are included in the AD, the specific fuel pump needing replacement is limited. In this case, the Part Number (P/N) is listed as P99C38-605, with the issue extending to a list of just over 100 serial numbers. Those numbers are listed in Appendix 1 of the EASA AD.
Thus, with a relatively small list of fuel pump serial numbers affected, this issue doesn’t appear to be as widespread as the long list of possibly affected variants might indicate.
