• The aircraft owner

• The aircraft manufacturer

• The FAA-certificated mechanic or repairman

• The pilot

What does the suffix '-R' indicate in the equipment list?

• Optional equipment item

• Standard equipment item

• Required item or equipment for FAA certification

• Additional equipment item

What must be completed to describe a major repair or alteration?

• A verbal report to the FAA

• A Repair Station record and/or FAA form 337

• A maintenance log entry

• A pilot's logbook entry

What is the first step in weight and balance computation?

What must be done if the TCDS lists the EWCG range as 'None'?

• No further checks are needed

• A fore and aft check for adverse loading must be made

• The aircraft must be grounded

• The pilot must be notified

What is the purpose of adverse-load CG checks?

• To determine the maximum payload

• An optional item

What is the significance of the leading edge mean aerodynamic chord (LEMAC) in CG calculations?

• It determines the aircraft's speed

• It is used to calculate the CG in percent MAC

• It indicates the fuel capacity

• It shows the maximum payload
