Airworthiness Directive · Amendment 39-9198 · McDonnell Douglas Corporation Airplanes
McDonnell Douglas Corporation Airplanes
Superseded. A later AD replaced this one: AD 95-21-04. Comply with the one in force.
This AD applies to McDonnell Douglas Corporation MD-11 Series (all).
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-11 series airplanes. This action requires modification of the support structure of the cargo liner. This amendment is prompted by a report of chafing and arcing in the vacuum waste exhaust heater that caused a spark to ignite the surrounding insulation blankets. The actions specified in this AD are intended to prevent fire and/or smoke due to chafing and arcing of the vacuum waste exhaust port heater.
