Airworthiness Directives; McDonnell

Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule; request for

comments.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) that is

applicable to certain McDonnell

Douglas Model MD–90–30 series

airplanes. This action requires an

inspection of the wiring of the primary

and alternate static port heaters for

chafing, loose connections, and

evidence of arcing, and to determine

what type of insulation blanket is

installed in the area of the static port

heaters; and corrective actions, if

necessary. This action is necessary to

ensure that insulation blankets

constructed of metallized MylarTM are

removed or protected from the area of

the static port heater. Such insulation

blankets could propagate a small fire

that is the result of an electrical short of

the static port heater and could lead to

a much larger fire and smoke in the

cabin. This action is intended to address

the identified unsafe condition.

DATES: Effective June 8, 2001.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of June 8,

2001.

Comments for inclusion in the Rules

Docket must be received on or before

SUPPLEMENTARY INFORMATION: As part of

its practice of re-examining all aspects

of the service experience of a particular

aircraft whenever an accident occurs,

the FAA has become aware of an

incident of smoke in the cabin on a

McDonnell Douglas Model MD–88

airplane. An investigation discovered

evidence of a fire adjacent to the rightside alternate static port heater. It was

discovered that the wiring of the static

port heater had shorted, which caused

an ignition source for the metallized

MylarTM (i.e.,

polyethyleneteraphthalate) insulation

blanket directly inboard of the heater

element. Insulation blankets constructed

of metallized MylarTM in the area of the

static port heater, if not corrected, could

propagate a small fire that is the result

of an electrical short of the static port

heater and could lead to a much larger

fire and smoke in the cabin.
