Due to decreased drag with the gear up, the tendency
will be to overshoot the approach.
gravity with the gear retracted is aft of the main
wheels. This condition will allow the aircraft to be
landed with the gear retracted and should result in a
minimum amount of structural damage to the aircraft,
providing the wings are kept level. It is recommended
that the fuel load be reduced and the landing made
with flaps fully extended on a hard surface runway.
Landing on soft ground or dirt is not recommended as
sod has a tendency to roll up into chunks, damaging
the underside of the aircraft's structure. When fuel
load has been reduced, prepare for a gear up landing
as follows:
1. Fuel load – Reduce.
2. Personnel
