FAA Repairman Certificate – Light-Sport Aircraft (LSA) Maintenance – Balloon Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• What gas is most commonly used to fill hot-air balloons for lift?
• Helium
• Heated air
• Hydrogen
• Nitrogen

Rationale: Hot-air balloons rely on heated air for lift, as it becomes less

dense than the surrounding cooler air.

• What is the primary lifting force in a gas balloon?
• Heated air expansion
• Buoyancy from lighter-than-air gas
• Propeller thrust 1 / 4

• Air pressure differentials

Rationale: Gas balloons use gases such as helium or hydrogen, which are less

dense than air, to create buoyancy.

• What type of envelope fabric is most commonly used in modern hot-air

balloons?

• Cotton
• Polyester
• Ripstop nylon
• Silk

Rationale: Ripstop nylon is strong, lightweight, and heat-resistant, making it

ideal for balloon envelopes.

• The FAA requires maintenance of a Light-Sport Balloon to be performed

by:

• Any aircraft owner
• A certificated LSA Repairman – Maintenance (Balloon)
• Any A&P mechanic only
• A Designated Pilot Examiner

Rationale: Only an LSA Repairman – Maintenance with a rating for balloons

can legally perform and approve maintenance.

• What is the function of the parachute valve on a hot-air balloon?
• Adds more fuel to the burner
• Releases hot air to control descent
• Measures envelope temperature
• Seals the fuel tank

Rationale: The parachute valve releases hot air from the top of the balloon,

allowing descent or landing control.

• Which FAA regulation governs the certification and maintenance of

Light-Sport Aircraft?

• Part 61
• Part 65
• Part 43
• Part 145

Rationale: FAA Part 65 outlines certification requirements for Repairmen and

mechanics, including LSA Repairmen.

• What is the minimum number of flight hours a balloon repairman must

have to qualify for a maintenance rating?

• 10
• 25
• None required for maintenance rating

D. 50 3 / 4

Rationale: The maintenance rating focuses on training in aircraft systems

and maintenance procedures, not flight time.

• Which of the following is a primary balloon system?
• Landing gear system
• Burner and fuel system
• Hydraulic system
• Electrical starter system

Rationale: The burner and fuel system are essential for controlling lift and

temperature in a hot-air balloon.

• What fuel is most commonly used in hot-air balloons?
• Jet A
• Avgas
• Propane
• Kerosene

Rationale: Propane is used because it is efficient, readily available, and

provides sufficient heat energy.

• The pilot light on a balloon’s burner system serves what function?
• Measures altitude
• Ignites the main burner flame
