The Marsh/Philippine Air Force OV-10 program at this time involved engine overhaul and modernization, installation of a new Hartzell propeller management system, and new 4 blade aluminum Hartzell propellers.*

Additionally the PAF also ordered new starter generators, generator control units with fault transformers, and new electrical power management units. In addition to the benefits offered by the new generator control units, the new the PAF new starter generators and control units can be easily supported compared to the old system.  The power management units (PMU) offers all new sealed D.C. power relays, and a series parallel starting system, which allows faster starting without the requirement for off base auxiliary power units (APUs or starter carts).

The PAF is also considering a new Eductor Exhaust System for inclusion into the current OV-10 fleet.  This offers reduced exhaust maintenance, cooler engine and accessory operations, and a reduced Infra-Red (IR) signature. Furthermore the Eductor Exhaust system also deletes the old engine hot section covers which restrict access to the engine fuel equipment. The new exhaust system offers the PAF the ability to service the engine nozzles without removing the engine from the aircraft, a real maintenance plus.

In the future, Marsh Aviation will be offering the PAF many additional upgrades that can be installed in the PAF OV-10A aircraft.  Upgrades such as new GPS systems with imbedded Communication, Navigation and ILS systems. A new ICS system will also be offered to support the new communication and navigation system.

The PAF has the opportunity to upgrade and modernize the OV-10A aircraft on a basis that will allow incremental improvement to the aircraft, and allow their staff to gain experience from the technology transfer offered by the new programs.

* PAF sources indicated that the PAF undertook and was responsible for the overhaul of the airframe and other systems not covered by the Marsh contract.
