AD NUMBER: 2008-22-02
MANUFACTURER: Maryland Air Industries Inc.
SUBJECT: Airworthiness Directive 2008-22-02 SUMMARY: We are adopting a
new airworthiness directive (AD) for Maryland Air Industries, Inc.,
Model Fairchild F-27 and FH-227 Series Airplanes.
This AD requires operators to modify their airplanes and revise
their inspection or maintenance programs to incorporate
instructions for maintenance and inspection of the fuel tank
systems, as appropriate, by December 16, 2008, using information
developed in accordance with Special Federal Aviation Regulation 88
(SFAR 88). This AD results from fuel system safety reviews done on
similar airplane models in accordance with SFAR 88.
These safety reviews identified potential unsafe conditions on
Model Fairchild F-27 and FH-227 series airplanes for which the type
certificate holder, Maryland Air Industries, Inc., has not
conducted SFAR 88 safety reviews, has not provided corrective
actions, and does not plan to do so.
We are issuing this AD to reduce the potential of ignition
sources inside fuel tanks, which, in combination with flammable
fuel vapors, could result in fuel tank explosions and consequent
loss of the airplane.
