PLT375: Approval for Return to Service
What code PLT375 covers, why the FAA tests it, and how to study Approval for Return to Service before your checkride.
Recall regulations - aircraft return to service
What this means for your checkride
No aircraft, airframe, engine, propeller, or appliance may be approved for return to service after maintenance, preventive maintenance, rebuilding, or alteration unless the required maintenance record entry has been made and any required repair or alteration form has been executed. Only certain persons may grant that approval, including the holder of a mechanic certificate or an inspection authorization as provided in Part 65. A person holding at least a private pilot certificate may approve an aircraft for return to service after performing preventive maintenance allowed under 43.3(g).
Return to service is the step that makes an aircraft legal to operate again, so applicants must know who may sign it off and what records are required first.
Doing the work is not enough; the aircraft is not returned to service until an authorized person makes and signs the required record entry.
Where to study it
A code on your test report is an area of deficiency. An authorized instructor must review it with you and endorse that review before you take the practical test, and the examiner may revisit it during the oral. Study it until you can explain it out loud, not just recognize the answer.
