U.S. Navy Prevents Corrosion by Adopting Av-DEC Gaskets

Upon discovering and applying Av-DEC gaskets, the customer found that there were no signs of corrosion during their regularly scheduled inspections. This led to a re-evaluation of their inspection schedule and a new 90-day interval being adopted.

To reduce the effects of corrosion on aircraft parts and components, maintenance and repair departments perform routine inspections. The standard procedure for one of Navy aviation customers was to inspect lower antennas on aircraft every 28 days and all other antennas every 56 days for signs of corrosion. The inspection process was time-consuming. It involved removing the antenna, conducting the inspection, treating corrosion, reinstalling the antenna and finally, resealing the perimeter. The resealing process generally took more than a day because the sealant required 24 hours to cure.

Upon discovering and applying Av-DEC gaskets, the customer found that there were no signs of corrosion during their regularly scheduled inspections. This led to a re-evaluation of their inspection schedule and a new 90-day interval being adopted. During the rescheduled inspection the antenna interfaces remained free of corrosion and further re-evaluations using data collected thereafter eventually allowed for an inspection schedule to be set for every 546 days.

With Av-DEC gaskets our customer exponentially improved inspection timelines. This caught the attention of the Original Equipment Manufacturer (OEM). Today, the OEM makes use of Av-DEC gaskets in the building and assembling of its military products.

The Benefits in Detail:

  • Lower maintenance and replacement cost
  • Increased inspection interval
  • Complete sealing against corrosion for the long-term
  • Increase in the lifespan of the associated equipment
