Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Landing gear,normal retraction/extension assembly - inoperative
Gear extension - not possible

Wheels up landing - performedPilot in command

Analysis

The acft was landed with the main gear retracted after attempts to extend them failed. After landing the acft departed the right side of the rwy. Post accident examination revealed that the secondary relief valve had failed in the hydraulic power pack. This prevented a build-up of pressure in the hydraulic system. The acft had only flown 57 hours since the hydraulic power pack was overhauled in July 1983.
