On 29 October 2011, a Boeing 737-800 on approach to Christchurch during the 68 year-old aircraft commander's annual route check as 'Pilot Flying' continued significantly below the applicable ILS minima without any intervention by the other pilots present before the approach lights became visible and an uneventful touchdown occurred. The Investigation concluded that the commander had compromised the safety of the flight but found no evidence to suggest that age was a factor in his performance. A Safety Recommendation was made to the Regulator concerning the importance of effective management of pilot check flights.
