EASA AD 2019-0291R1
SUPERSEDED BY EASA AD 2020-0283
Summary
EASA Airworthiness Directive 2019-0291R1 is an updated safety directive addressing fuel pump erosion issues on Airbus A330 and A340 aeroplanes, including the A330-941 variant. It mandates inspections and potential replacement of specific fuel pumps with part numbers 568-1-28300-101, 568-1-28300-103, and 568-1-28300-200 installed at designated locations to prevent fuel tank ignition risks. This directive applies to all manufacturer serial numbers of the affected models.
What Changed
This revision clarifies repair procedures for affected fuel pumps, specifically allowing repairs involving housing replacement per Eaton Aerospace Component Maintenance Manual 28-21-55. It also expands inspection requirements to all affected parts regardless of installation location and includes the A330-941 in the applicability. The directive remains an interim action pending development of a more erosion-resistant pump.
Why It Matters
This directive is critical for aviation operators and maintenance organizations to prevent potential fuel pump housing breaches that could lead to ignition sources inside fuel tanks, risking explosions and loss of aircraft. Compliance ensures continued airworthiness and safety by mandating repetitive inspections and corrective actions. It also affects maintenance planning and parts management due to inspection intervals and repair restrictions.
What To Do
Operators must inspect affected fuel pumps at specified intervals based on erosion levels and location, replacing or deactivating pumps showing severe erosion or breakthrough before next flight. Installation of affected parts is allowed only if they are serviceable and inspected accordingly. Compliance with inspection schedules must begin before 10,000 flight hours since installation or repair, with specific deadlines for pumps at different locations, and MMEL amendments must be made within 30 days after 17 November 2017 for applicable aircraft.
