Principal Structural Elements - Cessna 510 Mustang Structural Repair Manual

1. General
A. The Mustang is certified to the Damage Tolerance and Fatigue requirements. PSE's are defined as, "Those elements
which contribute significantly to carrying flight, ground, and pressurization loads, and whose failure could result in
catastrophic failure of the airplane."
B. Airplane principal structural element (PSE) inspections and safe life limits must be based on an engineering durability and
damage tolerance assessment (i.e., crack growth analysis for the airframe structure, and classical fatigue analysis for the
safe life limited landing gears and landing gear attachment fittings).
C. Repairs to PSE's must have a durability and damage tolerance assessment before returning the airplane to service.
Additionally, repairs to PSE's must be approved by the FAA or a DER authorized in damage tolerance.
D. The following structures are PSE's. They are listed to make sure structural inspections and safe life limits, as defined in the
Maintenance Manual, will remain valid after a field repair to a PSE.
