Analysis

A Cessna 140 lost control on takeoff ground run from rwy 21 and collapsed the right main landing gear. On the takeoff roll the acft veered to the right and as the acft approached the end of the rwy 21, it veered sharply back to the left collapsing the right main landing gear. The winds were reported from 060 deg at 7 KTS at the time of the accident. The pax indicated that a variable quartering tailwind condition existed and that the plt was not comfortable with taking off with a tail wind. He also indicated that the acft veered right on initial takeoff ground run and the plt's application of left rudder was ineffective. As the acft accelerated the left rudder input became effective and the acft headed for the left side of the rwy. The passenger stated, 'the PIC responded with full right rudder now to counteract the left veering tendancy.' The acft then veered back to the left collapsing the right main landing gear.
