Av8 Group develops STC Rain Erosion Shield for leading edge of B737:
9 March 2020 - The Av8 Group has developed a Rain Erosion Shield on the vertical stabilizers leading edge of B737 series aircraft.
The Supplemental Type certified shield offers a patch for the repair in two forms, aluminium for aircraft without HF installed and a Quartz composite patch for aircraft that have HF installed.
1.The patch is supplied complete with separate mounting plates.
2.The plates are installed in the inside of the leading edge and the patch is then installed with screws through the leading edge, into the mounting plates.
3.Access to the leading edge is facilitated via an access panel immediately above the fiberglass section.
4.To facilitate the installation of the mounting plates, an optional drill guide may be purchased to quickly and accurately drill the correct hole pattern for the mounting plates.
Currently the vertical stabilizer leading edge of the B737 series aircraft is a one-piece composite structure made from aluminium and fiberglass. Over time, the fiberglass abrades and wears away, requiring repair. The fiberglass requires several layers to repair, which can take up to a full week to remove the leading edge and repair the section.
"This advanced part replacement can be completed in just four hours, saving overall cost and downtime for the aircraft," stated Yoel Arnoni, CEO, Av8 Group.
