SUMMARY: We propose to rescind airworthiness directive (AD) 2009-18-19. This

proposed AD results from mandatory COlJtinuirlg airworthiness infonnation (MCAI)

issued by EASA, to rescind EASA AD 2010-0083. The MeAl specifies the following:

It has been assessed that multiple 1\TRV [non return valve] failures in

combination with certain trapped fuel cases could potentially increase the

quantity ofllllusable fuel on the aeropla11c, possibly leading to fuel

starvation which could result in engineJ in-flight shut down and would

constitute an unsafe condition. To prevJnt and detect this condition, EASA

issued EASA AD 2010-0083.

Based on in service experience, mainly Ion the results of the operational

test required by EASA AD 2010-0083, !Airbus has performed a safety

analysis on the NRV to check if the saf6ty objectives are met.

This analysis of the Collector Cell motile flow line NRV, taking into

aCCOlll1tall failure scenatios, conclUdeslthat the previous non compliance

can be alleviated. Consequently, no unsafe condition exists any more on

the atJected NRV.

For the reasons described above, EASA! AD 2010-0083 is cancelled

The proposed AD \vou1d rescind the parallel F1A AD 2009-18-19.
