Glider and Banner Tow Hook — New Product!

Safer than the old Schweizer tow hook!

New design and instructions address tow hook jamming problems at high tow an­gles. The McFarlane tow hook is engineered with increased leverage to release with less effort than the Schweizer tow hook in emergency situations where the load is at an extreme angle.  It is also improved to maintain the tow ring position to reduce release force.  A new roller release design also minimizes release force.

The following articles further describe the problem of tow hook jamming at high tow angles.  McFarlane Aviation Products has not verified the technical accuracy of these articles and they are presented for their qualitative description of the problem only.

Flap Track Wear Gauge for Cessna Aircraft

This convenient gauge determines if a Cessna flap track is worn beyond service limits.  To use the gauge, simply run the gauge plug along each slot in each flap track to verify that the gauge will not enter the slot. If the gauge enters a slot at any point, the track is worn beyond ser­vice limits. It works for all single engine Cessna aircraft except 140A, 170A and 195.
