SUBJECT: Airworthiness Directive 2010-23-05

SUMMARY: The FAA is superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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:

Prompted by [an] accident the FAA published SFAR 88 (Special Federal Aviation Regulation 88).

Fuel Airworthiness Limitations arising from the required systems safety analysis are items that have been shown to have failure mode(s) associated with an `unsafe condition'. These are identified in Failure Conditions for which an unacceptable probability of ignition risk could exist if specific tasks and/or practices are not performed in accordance with the corrective actions(s) developed by the TC [type certificate] holder. 

The FAA is issuing this AD to require actions to correct the unsafe condition on these products.
