Kevin, et al,

I did a NTSB search from 1990 to present for Lancair accidents in Oreg= on -=20 there were 11 and none involved brake line failure.

I flew my 320 from 1996 until 2013 with Nylaflow brake lines=20 that arrived, along with fittings, with my 1989 kit (over 1200=20 landings). However, the lines in the stub wing to the brake were shea= thed=20 with Tygon tubing to protect against nicks and abrasion and Adele clamps we= re=20 used to firmly support the lines about 6-8 inches from the b= rake=20 housing by screwing the clamps to the rear of the wheel casting.&= nbsp;=20

For all I know, the buyer is still using those lines.

It is possible that unsupported lines flop around in the wind whe= n the=20 gear is out and the line is weakened at the brake-to-line fitting

John,
That could have been ugly. A friend of mine= with=20 a Glasair had a rejected takeoff on a short runway. As he turned of= f the=20 runway, his plastic brake line melted and the 5606 hit is brake=20 disk.
