             This Airworthiness Directive becomes effective on 17 March 2005.
Background:  In 1973 the then NAA issued AD/PA-23/56 as a result of a report of a fatal accident related to the breakdown of the turbocharger oil reservoir following a fire in the engine nacelle.  This was followed by FAA AD 74-06-01, which has now been superseded by AD 2005-01-10.  The actions specified in this AD are intended to prevent turbosupercharger oil reservoirs and associated hoses with inadequate fire resistance from failing when exposed to flame or exhaust gases.  This failure could lead to an in-flight fire within the nacelle area penetrating the firewall and subsequent failure of the wing spar.
