That article that NewsWatcher posted a link to is a bit strange.
Why would the instructor be commenting on his landings? Unless I'm missing something his (on airport) landings are completely irrelevant to this incident. In any case why did the instructor allow him to go solo if he wasn't happy that his landings were safe?
They also mention that he mad numerious previous errors, including fuel errors. If they felt that these were serioius enough, then surely they were serious enough to require further training, until they were happy with him, before letting him hire the plane solo?
Does the club not owe a duty of care to the public at large to make sure that they don't hire an aircraft to someone that they have serious concerns about their safety? If not, then surely they owe a duty of care to the aircraft insurers not to hire it to someone they has concerns about.
