Cessna F177RG Cardinal, G-AZVP
When the pilot initially lowered the landing gear, the green ‘down-and-locked’ light did not illuminate; this was due to a misaligned downlock microswitch on the left main landing gear. The pilot operated the emergency hand pump to manually extend the gear, on landing the nose leg collapsed. No other faults were found with the landing gear system and it is possible that during the manual extension there was insufficient pressure applied to fully lock down the nose leg.
