## Analysis

UPON ARRIVAL AT THE AIRCRAFT, THE PILOT NOTED THAT THE NOSE  GEAR STRUT WAS UNDER INFLATED. THE PILOT, WHO IS TRAINING TO BE AN A&P MECHANIC, DIAGNOSED THE PROBLEM AS AN OIL LEAK. HOWEVER, TO AVOID ABORTING THE FLIGHT, HE INFLATED THE STRUT WITH AIR ONLY AND TOOK OFF. ON LANDING, IN A STRONG CROSSWIND, THE NOSE STRUT COLLAPSED CAUSING THE AIRCRAFT TO WHEELBARROW. THE PROPELLER TIPS AND THE RIGHT WING TIP SCRAPED THE RUNWAY CAUSING MINOR DAMAGE.
