Plain English Summary

2/10 complexity

This is a safety rule for Cessna T337G aircraft (twin-engine planes). It requires owners to securely bolt the rear (fifth) seat to the cabin floor before the aircraft can legally fly.

What must happen:

The back seat must be "positively attached" (firmly fixed/bolted) to the floor structure using an engineering plan approved by the Secretary (the relevant government official)
One acceptable way to do this is following a specific technical drawing from Rex Aviation (Drawing No. RA-C-1341)
This modification must be completed before the plane receives its Certificate of Airworthiness (the official safety certificate required to fly)

Why this matters: This prevents the rear seat from breaking loose during turbulence or in an accident, protecting passengers from serious injury.
