STC Approval of Passenger to Freighter Conversions

The majority of narrowbody commercial aircraft freighters flying today and roughly half of the widebody fleet were originally delivered new from the manufacturer as passenger aircraft. These aircraft were extensively modified to carry cargo by what is commonly referred to as a Passenger to Freighter conversion (PTF or P2F). Two primary modifications are required to be classified as a freighter aircraft. The floor panels as well as the structure beneath must be strengthened to handle heavier floor loads and the standard passenger doors must be enlarged to accommodate shipping containers. A P2F conversion will make major modifications to an aircrafts approved Type Certificate (TC). Since the TC certifies the airworthiness of the aircrafts design, a Supplemental Type Certificate (STC) must be obtained to attest to the airworthiness of any major modifications.


FIRST OF TYPE STC APPROVED ON BEHALF OF BANK
The experts at CV are proud to have successfully managed the first of type passenger to freighter conversion and subsequent Supplemental Type Change (STC) approval of a Dornier 328-120 Turboprop aircraft.

At the onset of our engagement we found the aircraft disassembled and only partially modified. The previous owner had declared bankruptcy in the middle of a freighter conversion attempt without having obtained any of the required FAA Type Change approvals. Prior to our engagement the only option available to the bank was to sell the aircraft for the parts value at a substantial loss.

The experts at CV were able to manage the completion of all overdue maintenance as well as obtain the proper regulatory approvals to protect the bank's investment and enable the sale of the aircraft.
