N96299, a Cessna 172Q, was inbound on the localizer and was executing the ILS approach to runway 9. The private pilot in the left seat was wearing an instrument hood, and the flight instructor in the right seat was maintaining a visual lookout. N5129C, a Cessna T210N, had completed the VOR-A approach, and had entered the traffic pattern for landing on runway 9.

Both airplanes landed safely. The 172 had minor damage. The 210 sustained substantial damage, including a destroyed right wing upper spar cap and a damaged right aileron that reduced roll control.
