# Emergency exits (over-wing small and slightly
larger exits) the clearance has to be increased,
vertical separation between seats at these locations
must not reduce below 10” (25.5cm).

impact their head on the seat in front under heavy
braking the row of seat after emergency exits must
be able to break forward.

• - Over-wing emergency exit points, in emergency,
people will climb over the seats to get out and if
seats were to fold a crush would hamper the
evacuation, so these seat backs will not fold
forward.

seat numbers. Maximum numbers of seats
abreast in a single aisle aircraft is 3.

functioning and be correctly lubricated.

Repair
-return complete belt or harness to the manufacturers
-some operators have approval to carry out their own
repairs, but confined to stitching and fitment replacemen
Cleaning

with warm air.
Colour Change
- by dyed (to match the cabin decor) permission
- must be obtained from the belt manufacturer.

Proof Testing
• - After repair, specified in the maintenance
schedule, part of the belt using material in a load
bearing capacity should be proof tested to a
specific load.
• - load and the method of testing is specified by
the manufacturer.
• - but in general test load should be ½ of the
certified strength of the member under test.
• - The release should work at 1.5g.

Storage
• - belts and harnesses should be stored in clean, dry
conditions at normal room temperature and away
from direct sunlight.
• - Harnesses, other than new articles in their original

Storage
- storage period for new original packaged equipment
before they require testing is specified by the
manufacturer.
Records
- - A record should be kept in the bay of all work carried
out on the harness.
- - Harnesses should be serial numbered to identify
them against their record card.

The LOPA also gives the
minimum quantity for
dispatch of aircraft.
Each particular aircraft‟s
LOPA has to be referred
