RJN 2120-AA64

Airworthiness Directives; B/E Aerospace Pro ective Breathing Equipment Part Numb·

119003-11 Installed on Various Transport AirPlanes

AGENCY: Federal Aviation Administration (I)' DOT.

ACTION: Notice of proposed rulemaking (NPRM).

SUMMARY: We propose to adopt a new airworthiness directive (AD) for various

transport airplanes equipped with certain BIE Aerospace protective breathing equipmen

(PBE) units. This proposed AD would require rlmOving affected PBE units. This

proposed AD resuhs from reports of potentially defective potassium superoxide caniste

used in PBE units, which could result in an exothermic reaction and ignite. We are

proposing this AD to prevent PBE units from i~iting, \vhich could result in a fire and

possible injury to the flightcrew or other persOll

DATES: We must receive comments on this pr~posed AD hy [INSERT DATE 4S

DAYS AFTER DATE OF PUBLICATION IN FHE FEDERAL REGISTER].

ADDRESSES: You may send comments by an~ of the following methods:

• Federal eRulemaking Portal: Go to hu6:1/ww,\,.regUlations.gOv. Follow the

instructions for submitting comments.

• Fax: 202-493-2251.

• Mail: U.S. Department of Transportation, Docket Operations, M-30, West

Bui.lding Ground Floor, Room W12-l40, 1200 New Jersey Avenue SE., Washington, D
