This collection of information involves the mandatory reporting and recordkeeping of maintenance, major modifications, repairs, and alterations performed on U.S. civil registered aircraft. The reporting and maintenance recording required by FAR 43 may only be done by certified mechanics, repair stations, and air carriers authorized to perform maintenance. Pilots are also authorized to perform and record preventive maintenance, however, the authorization applies only to those pilots who own or lease their aircraft for private operation for preventative maintenance only. The reporting and maintenance recordkeeping requirements of FAR 43 is a ongoing process and initiated on occasion as needed at the time of maintenance, preventive maintenance, rebuilding and alteration of an aircraft airframe, aircraft engine, propeller, or appliance. All information on completed 337 forms are submitted to FAA division AFS-750 through electronic process or paper copy. Information collected is aircraft data arranged by registration âNâ number, owner name and address, with certificate number of the person accomplishing the work. The form also contains detailed information of the work accomplished. The information is then recorded in the aircraft official database record to be kept indefinitely. This is accomplished to enhance safety by ensuring quality workmanship and parts are utilized for the continued operational safety of the flying public and passengers aboard the aircraft and on the ground.
This information is collected for all aircraft undergoing maintenance, repair or alteration. Some allowances have been given to FAR part 121 air carriers to authorize an alternative method of reporting major repairs and alterations. This alternative method is a record keeping system approved by the local office through company procedures to maintain and approve the repairs and alterations for their aircraft in a permanent record. This is only accomplished by 80% of the certificated air carriers. The remaining 20 % still utilize Form 337 for these modifications to their aircraft under their operational authority.

The only change to this submission is the increased aircraft operating in the NAS. The 337 Form is utilized the same way as before and required by the regulations. There have been no program changes since the last submission. The part 43 Form 337 numbers increased due to more information but strictly on the requirement for the recordation of major repairs or changes in a growing number of aircraft operating today. However, we have added information to correctly capture the Part 121 recordkeeping alternative method. Part 121 carriers utilize engineering data and the form 337 is used as a capture of data, in the aircraft records, also a requirement of the regulations.
