OV-10 Service Life Extension Program (SLEP) Project of the Philippine Air Force
With the OV-10A Bronco light attack aircraft ageing rapidly and many of the PAF's examples going to the boneyard without the ability to replace them with new aircraft, the service understood that something has to be done with what they have while they are still looking for ways to replace the OV-10 fleet with a new aircraft.
The Service Life Extension Program (SLEP) was meant to address this issue in the short to medium term, and an initial batch of 6 aircraft were eyed to undergo the upgrade works.
This resource page discusses the project which was undertaken as part of the Capability Upgrade Program of the AFP Modernization Program under RA 7898.

Overview:
With the OV-10A Bronco light attack aircraft ageing rapidly and many of the PAF's examples going to the boneyard without the ability to replace them with new aircraft, the service understood that something has to be done with what they have while they are still looking for ways to replace the OV-10 fleet with a new aircraft.

A budget of Php256,000,000.00 was set aside for the project, which will involve overhauling the engines, acquiring spare engines, acquiring new 4-bladed propellers to replace the existing ones, re-wiring of the aircraft, structural enhancements, and improvement on the aircraft's avionics.
2 bidders submitted their proposals but the proposal from the Joint Venture of Marsh Aviation and Aeromart won. A contract was signed by the DND on 20 August 2004, with the project pushing ahead with a target completion date of 2 years.
An initial batch of 4 propellers and 4 overhauled engines were delivered as of 05 February 2005, and a second batch of 4 overhauled engines and 4 propellers were delivered as of 19 September 2005. A third batch of six propellers were delivered on 24 October 2005, while the last batch involving 4 overhauled engines were delivered by 2006.
The project was declared completed as of September 2006 with all 6 aircraft upgraded to what they call the OV-10M (Modified) standard, which passed testing and acceptance by the Philippine Air Force.
While not part of this upgrade program, the PAF continued to improve the OV-10M several years later, including adding the capability to drop GBU-12 Paveway II and GBU-49 Enhanced Paveway II smart bombs. The improved avionics and structural upgrades done as part of this project made it easier for such upgrade to be made.
