Probable cause

The experimental aircraft association's (eaa's) inadequate procedure for providing control and separation of aircraft, its inadequate surveillance of the operation, and inadequate coordination by ground personnel. Related factors were: the ground personnel's lack of experience in the type of operation, and the presence of other aircraft.

Analysis

Drg an annual experimental acft assoc (eaa) fly-in, a parade-of-flt demonstration (demo) was started, involving antique & classic acft. Air traffic ctl (ATC) responsibility for the opn was assumed by eaa, iaw a cert of waiver to 14 CFR 91. The demo bgn by lining up acft nr rwy 36 to tkof in sequence. When signaled, each plt would take off, fly a pattern, then lnd on a grass strip beside rwy 36 & be drctd to the parking area. After a pattern & lndg, the plt of Piper E-2, N2414, apchd rwy 36 (1800' fm the rwy threshold) as he was taxiing to park. At the aprx same time, a ryan PT-22, N54403,was being prepared for takeoff. An official (flagman) motioned for the E-2 to cross the rwy, but it wasn't equipped withbrakes, so the plt taxied slowly. The flagman motioned for the E-2 plt to expedite, but the plt contd to taxi slowly to avoid acft ahead. Meanwhile, the PT-22 plt bgn taking off & did not see the E-2 ahead. Shortly after lift-off, the PT-22HIT the E-2, damaging both acft. The E-2 plt saw the PT-22, moments bfr impact.
