1. What is the maximum takeoff weight allowed for a Light-Sport Aircraft
(Weight-Shift Control)?
a) 1,100 pounds
b) 1,320 pounds
c) 1,430 pounds
d) 1,200 pounds
Rationale: The FAA defines the maximum takeoff weight for a land-
based Light-Sport Aircraft as 1,320 pounds (600 kg).
2. What type of control system does a weight-shift control aircraft use?
a) Conventional control surfaces
b) Shifting pilot and wing mass relative to each other
c) Ailerons and rudders
d) Computer-assisted fly-by-wire
, Rationale: Weight-shift control aircraft are controlled by changing
the center of gravity relative to the wing through pilot movement.
3. What is the maximum stall speed permitted for an LSA in the landing
configuration?
a) 61 knots CAS
b) 55 knots CAS
c) 45 knots CAS
d) 40 knots CAS
Rationale: FAA regulations set the maximum stall speed for an LSA at
45 knots calibrated airspeed (CAS).
4. What fuel is most commonly used in weight-shift control aircraft
engines?
a) Diesel
b) Jet A
c) Automotive gasoline or 100LL avgas
d) Ethanol only
Rationale: Most LSA engines like the Rotax 912 series use either
unleaded automotive gasoline (MOGAS) or 100LL aviation gasoline.
5. What type of engine is most common in LSA weight-shift control
aircraft?
a) Turboprop
b) Inline six-cylinder
c) Rotax four-stroke or two-stroke
, d) Diesel rotary
Rationale: Lightweight, efficient Rotax engines are most commonly
used due to their power-to-weight ratio and reliability.
6. What FAA regulation defines the privileges and limitations of a Light-
Sport Repairman?
a) Part 91
b) Part 61
c) Part 65, Subpart K
d) Part 145
Rationale: Part 65, Subpart K covers repairmen certificates, including
privileges for LSA maintenance and inspection.
7. What document must be referenced to determine if a part is approved
for installation on an LSA?
a) FAA TSO list
b) Type Certificate Data Sheet
c) Manufacturer’s maintenance manual or ASTM consensus standard
d) Aircraft Bluebook
Rationale: LSAs are built to ASTM consensus standards, and parts
approval is guided by manufacturer specifications.
8. What action must a repairman take after performing a major repair on
an LSA?
a) Notify the NTSB
b) Retest the aircraft per Part 91
, c) Make a logbook entry and ensure it meets manufacturer and FAA
requirements
d) Apply for a new airworthiness certificate
Rationale: A proper maintenance record entry must describe the
work performed and certify airworthiness per 14 CFR 43.9.
9. What does ASTM stand for?
a) Aeronautical Standards for Technical Maintenance
b) American Society of Testing Mechanics
c) American Society for Testing and Materials
d) Aviation Standards and Technical Manuals
Rationale: ASTM develops voluntary consensus standards used for
LSA certification and maintenance.
10. What type of airworthiness certificate does an LSA carry?
a) Standard airworthiness certificate
b) Restricted airworthiness certificate
c) Special airworthiness certificate (Light-Sport category)
d) Experimental certificate only
Rationale: LSAs operate under a special airworthiness certificate in
the Light-Sport category.
11. How often must an LSA used for compensation or hire be
inspected?
a) Annually
b) Every 100 hours
