RUAG Aviation completes Twin Otter re-life project

Emmen, Switzerland, 10 February 2014

A 33 year old DHC-6 Twin Otter has received a new lease on life, following a comprehensive overhaul and upgrade project completed by RUAG Aviation at their facility in Bern-Belp, Switzerland. The re-life project was performed on behalf of Blue Bird Aviation Yemen, which owns the DHC-6 Twin Otter 7O-ADI MSN 664 and approached RUAG Aviation following successful experiences with engine and component overhauls.

Corrosion repairs were carried out on the wings, improving the aircraft’s safety and lifespan, and enabling the customer to avoid the unnecessary costs and downtime of complete wing replacements. The re-life programme extends the wing’s use for a further 33,000 flight hours. To further improve the Twin Otter’s life cycle, the cockpit of the 33 year old aircraft was fully modernised. Garmin 650/750 touchscreen navigation displays were integrated by RUAG Aviation, along with an Aspen 1000 avionics suite that incorporates an autopilot system and a new weather radar.

“The upgrades and modifications performed by RUAG Aviation have effectively made a new aircraft out of the Twin Otter 7O-ADI MSN 664,” says Simon Hafele, General Manager of RUAG Aviation’s Bern/Belp facility. “With the aircraft’s new modern avionics and the re-life STC of its wings, the customer can confidently continue operating their Twin Otter for many more years to come.”

The entire avionics engineering, manufacturing of cable looms, installations and final testing involved in the re-life programme were completed by RUAG Aviation.

RUAG Aviation is a certified Part 21J EASA Design Organisation, Part 21G EASA Production Organisation and Part 145 EASA Maintenance Organisation.
