Narrative:

While flying the localizer back course runway 27L at pontiac, mi, we were setting up for a stabilized final approach. On short final we were slightly left of course so I corrected to the right. Inside the threshold I began to flare the aircraft too high. The airspeed decreased and the wingtips began to bank back and forth. At this point, the captain took over. The tip tanks began to severely wobble back and forth. When we taxied in we discovered that the tip tanks had scraped the runway surface. Callback conversation with reporter revealed the following information: the reporter was flying the lear 24. He says that he was an 'other crewmember,' not the first officer. He has not heard from the FAA on this. He was very reluctant to talk about this.
