The Endorsement That Didn't Transfer
A pilot earned his sport pilot certificate two years ago in a fixed-gear, fixed-pitch LSA. Six months ago he received training and a logbook endorsement for retractable landing gear and a manual controllable-pitch propeller in a specific make and model - call it the 'Aero 200RG.' He has since flown that Aero 200RG about 40 hours. A flying club now offers him a different LSA, the 'Skyline 300RG,' which also has retractable gear and a constant-speed propeller. The club's scheduler says, 'You've got the retract and prop endorsements, so you're good to go in anything with those systems.' The pilot has never flown a Skyline and has no time in type. The Skyline's operating limitations permit sport pilot operation and it meets all LSA limits.
1. Do his existing endorsements authorize him to act as PIC of the Skyline 300RG? Explain the scope of the endorsements.
Read the worked answer
No. The retractable-gear and controllable-pitch-propeller endorsements are make-and-model specific. His endorsements were issued for the Aero 200RG; they do not transfer to the Skyline 300RG.
The scheduler's 'anything with those systems' reasoning confuses a system category with an aircraft type. The training and endorsement exist precisely because each type's gear and propeller systems - extension speeds, emergency procedures, governor behavior, warning systems - differ. He would need additional training and a new endorsement for the Skyline before acting as PIC.
The Skyline being a compliant LSA with the right systems removes the aircraft-level barrier but not the endorsement-level barrier.
2. What training should he expect before receiving the Skyline endorsement, and what should he verify about the aircraft itself?
Read the worked answer
Training (ground and flight):
- Normal and emergency gear operation: extension/retraction, gear warning, alternate extension, gear-up landing procedure, and the type's gear speed limitations.
- Propeller/constant-speed operation: governor behavior, manifold pressure/RPM management, what happens on a governor failure, and the correct response.
- Differences from the Aero 200RG: systems layout, speeds, handling, and performance.
- A checkout to demonstrate proficiency, after which the instructor endorses his logbook for the Skyline make and model.
Aircraft verification:
- Confirm the operating limitations permit sport pilot operation and the intended flight (day/night, VFR).
- Confirm maintenance and inspection status are current.
- Review weight and balance and performance for the planned flight - a different type has different numbers; his Aero 200RG habits may not transfer.
3. He is impatient and wants to 'just do a couple of patterns' in the Skyline without an endorsement. What is the regulatory and safety case against that?
Read the worked answer
Regulatory: Acting as PIC without the required make-and-model endorsement is a violation, even for a single pattern. The endorsement is a condition of the privilege, not a suggestion.
Safety: A 'couple of patterns' in an unfamiliar retract with a constant-speed prop is exactly the scenario where things go wrong:
- Gear forgotten on landing or retracted below safe speed.
- Prop control mishandled during approach or go-around, causing an overspeed or loss of performance.
- Unfamiliar speeds and sight picture on approach.
A checkout is short and inexpensive compared with a gear-up landing or an enforcement action. The right answer is to complete the training and endorsement for the Skyline - the endorsements he holds cover a different airplane and do not substitute.
