• What is the maximum takeoff weight allowed for a Light-Sport Aircraft

(Weight-Shift Control)?

• 1,100 pounds
• 1,320 pounds
• 1,430 pounds
• 1,200 pounds

Rationale: The FAA defines the maximum takeoff weight for a land-

based Light-Sport Aircraft as 1,320 pounds (600 kg).

• 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 1 / 4

Rationale: Weight-shift control aircraft are controlled by changing

the center of gravity relative to the wing through pilot movement.

• What is the maximum stall speed permitted for an LSA in the landing

configuration?

• 61 knots CAS
• 55 knots CAS
• 45 knots CAS
• 40 knots CAS

Rationale: FAA regulations set the maximum stall speed for an LSA at

45 knots calibrated airspeed (CAS).

• 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.

• 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 2 / 4

d) Diesel rotary

Rationale: Lightweight, efficient Rotax engines are most commonly

used due to their power-to-weight ratio and reliability.

• 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.

• 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.

• 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 3 / 4

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.

• 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.

• 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.

• How often must an LSA used for compensation or hire be

inspected?

a) Annually

b) Every 100 hours
