Greenwich Air Begins

Aging Aircraft Program

MIAMI - Miami-based Greenwich Air Services, an independent aviation maintenance facility, has begun an Aging Aircraft Program.

As aircraft such as the Boeing 727 approach mandatory thresholds, certain inspections and modifications are required. Greenwich Air Services' program responds to these requirements.

Close to half of the 727s currently operating are more than 20 years old. Estimates reveal that there are approximately 1,650 727s flying today throughout the world. Thus, more than 800 were built prior to 1970.
