Question 7

What must a flight crew ensure while landing or taxing an aircraft with possible deflated or damaged tires?

Answer 7

Reference the Taxi with Deflated or Damaged Tires limitation section for the following:
- If maximum one tire per gear is deflated (consider three gears),
maximum taxi speed during turn is 7 knots

• If two tires are deflated on the same main gear (maximum one main gear), maximum taxi speed is 3 knots
• Maximum nose wheel steering (NWS) angle is 30°
• In addition, if tire damage is suspected, the flight crew must ask for an aircraft inspection prior to vacating the runway or taxi. If ground crew suspects tire burst may damage landing gear, maintenance action is required.
