Requirements
Weight and balance is of such vital importance that each
mechanic or repairman maintaining an aircraft must be
fully aware of his or her responsibility to provide the pilot
with current and accurate information for the actual weight
of the aircraft and the location of the center of gravity.
The pilot in command has the responsibility to know the
weight of the load, CG, maximum allowable weight, and
CG limits of the aircraft.
The weight and balance report must include an equipment
list showing weights and moment arms of all required and
optional items of equipment included in the certificated
empty weight.
When an aircraft has undergone extensive repair or major
alteration, it should be reweighed and a new weight
and balance record started. The A&P mechanic or the
repairman responsible for the work must provide the pilot
with current and accurate aircraft weight information and
where the new EWCG is located.
