Why are your TT Straps STC’d and not PMA’d?

Our TT Straps are drop-in replacements with no aircraft modification required. We acquired FAA STC to be able to attain STC validation by EASA, and Brazil and other foreign civil aviation authorities. STC is considered to be higher level of certification so the FAA asked us to sell them as STC’d parts. This  then required us to also attain Transport Canada STC validation for the Bell 206 and medium Bell straps.

Do we need to fill out a 137 form?

Yes, we ask for and put the helicopter registration number and serial number on the invoice along with an STC permission statement. We can make up a separate STC permission statement upon request. We can create an STC permission statements at any time even well after shipment. We are happy to create and send you an STC Permission Statement if it was not supplied with the straps or in cases when the straps are swapped to another helicopter.
