PL-97, Original, dated Jun 26, 1998
Former Policy Letter 19, dated Feb 11, 1986

 

PURPOSE:

The purpose of this policy letter is to provide standardized requirements for Flight Attendant seats.

 

DISCUSSION:

In order to evaluate and analyze the extent of inoperative flight attendant seats, a three-year test program was implemented effective with the issuance of the original Policy Letter 97. Operators would provide AFS-260 with information on inoperative flight attendant seats, to include inoperative dates, malfunctions, and corrective actions. The original policy letter 97 reformatted PL 19 with changes to policy for repair category from “no specific repair category” to a more restrictive category A for aircraft with only one flight attendant seat, category B for aircraft with more than one flight attendant seat, and category C for aircraft with seats in excess of that required by Federal Aviation Regulations.  Displacement of a flight attendant from a flight attendant seat to a passenger seat usually precludes or restricts access to equipment required by the FAR's such as the flashlight, passenger address system, and interphone. Additionally, being seated in a passenger seat could expose the flight attendant to a greater potential of being injured during a crash due to the lack of a shoulder harness. Considering that the primary responsibility of a flight attendant is to open escape doors and assist passengers in the evacuation of an aircraft following a survivable accident, it is imprudent to jeopardize the performance of such a key person during a time his/her services may be crucial to the evacuation of injured and uninjured passengers on the aircraft.

 

Revision 4: Revises PL 97 to provide additional MMEL relief for those aircraft where a Flight Attendant is not required by regulationsRevises POLICY statement by deleting references to “14 CFR Part 121 and 135” since policy is applicable to other operations.

 

Revision 3: Revised PL 97 to provide additional MMEL relief for operators other than holders of an air carrier or commercial operator certificate.

 

Revision 2: Further clarified where a displaced flight attendant should be seated. The displaced flight attendant should occupy the seat nearest to the original position so as to most effectively perform assigned duties. In the case where a required position is on one side of a dual seat, ideally, the best position for the displaced flight attendant would be the adjacent flight attendant seat.  Revision 2 also creates a new sub-category, "All Cargo Configuration" with a category D repair schedule.

 

Revision 1: Incorporated editorial corrections which included changing proviso 1(b) under aircraft with more than one flight attendant seat to correspond with (b) under aircraft with only one flight attendant seat.

Flight Operations Evaluation Board (FOEB) Chairman should incorporate the following standard MMEL provisos in all applicable MMELs through the normal FOEB revision process.
