13. Have you ever faced with gear problems in your practice?

14. Will you recollect any accident or incident that occurred because of undercarriage malfunction?

Undercarriage system plays vital role in providing safe completion of take off and landing. So, any malfunction or deficiency in it can pose risk to structural integrity of the aircraft and thus for its controllability and safety.

The landing gear problems may be caused by variety of reasons:

Technical reasons such as

· Hydraulic system failure

· Electrical system problems

· Tire burst due to

√ overheating (may be because of extremely hot weather with the temperature above 50 degrees; it leads to heating of the concrete and as a result in overheating of tire while rolling at high speed)

√ rough landing

√ overweight landing

√ rejected take off (sharp applying of brakes at high speed can result in tire burst)

· Mechanical failure ( the rest of the system may work but the actual mechanism fails to operate due to metal fatigue)
