The hatch was missing on the amphibious plane built by Tauranga man John Borman

A widely respected pilot who died after his plane plunged into Lake Taupo in front of crowds of summer holidaymakers had repaired it with sticky tape just hours before the crash.

John Borman, a New Zealand fixed-wing formation flying representative, was seriously injured and later died after the kitset amphibious plane he had spent thousands of hours building flipped and crashed at Lake Taupo. His wife Noeleen, the only passenger, suffered facial injuries and concussion.

In a just-released report, Civil Aviation Authority safety inspector Tom McCready found Borman, 60, had used strips of sticky tape to repair the nose landing gear doors and locker hatch of the high-performance Seawind after they were damaged when the plane struck a boat's wake during an earlier take-off attempt. A ball end in the retraction mechanism was also broken. "After that damage, the aircraft was technically and legally unserviceable," the report says.

Even so, Borman made three more attempts to get the plane airborne, declining offers from several aircraft engineers to help repair the damage.

Instead, he fitted a replacement ball end part and strapped a folded "Danger" sign, from a construction site, over the damaged nose-wheel doors, using a single piece of sticky tape on each side. He also secured the nose locker hatch, which had been blown off by the impact, with tape.

Said McCready's report: "This method of securing the hatch is even more remarkable, given the aircraft design, with the propeller immediately above and behind the cabin... severe propeller damage would have been likely if the hatch had [broken away] during flight."

While the plane was not deemed airworthy, the precise reason for it crashing during the fourth take-off attempt could not be determined. The report said Borman may have made several uncharacteristic decisions in order to get home to Tauranga.

It said Borman had previously used sticky tape to repair damage on another Seawind before a successful land-based take-off and may have "gained confidence" from that.

While Borman was experienced - he had flown here and in the United States and had accomplished more than 200 water landings - neither he nor his wife were wearing lifejackets. "If it hadn't been for the prompt intervention of bystanders, a second fatality may have been likely," said McCready's report.

Borman, who was trapped in the cockpit of the plane and died a day after the crash in 2005, and Noeleen were rescued by Taupo boatie Tony Landl and his son Jan.
