While attempting to land a tailwheel airplane in a crosswind at a private uncontrolled field, you lost control and the aircraft "ground-looped."

a. The right wingtip was damaged to the extent that it will have to be repaired or replaced before further flight. Do you have to notify any government agency of this event? Explain your reasoning.

b.During the course of the ground loop, the right main landing gear leg also failed. Now do you have to notify any government agency of this event? Explain your reasoning.

c.When the landing gear failed, the propeller struck the ground and was bent. Now do you have to notify any government agency of this event? Explain your reasoning.

d. A subsequent tear-down inspection of the engine reveals that the prop strike bent the crankshaft. Now do you have to notify any government agency of this event? Explain your reasoning.

e. During this sequence of events, your head was banged against the aircraft's structure. Although you did not lose consciousness, you had an extreme headache and dizziness and were hospitalized for treatment for a concussion. Now do you have to notify any government agency of this event? Explain your reasoning.
