More money to keep Hercules flying

3839

The South African Air Force (SAAF) has upped its bill to keep the venerable Lockheed Martin C130BZ flying by another R13 million. The SAAF last week awarded Denel Aviation an extension of an existing contract to provide product support services for the aging aircraft.

According to the Armscor Bulletin System, the cost of keeping the Hercules flying – fuel and crew excluded – now stands at at least R226 909 250 since early 2007 in addition to a minimum of R3 686 241.08 charged in hangarage for the damaged aircraft #402 from 2005 until last year.

The SAAF C-130 fleet consists of seven platforms (401 – 407) purchased in 1963 before a US arms embargo was imposed on South Africa’s apartheid government and five received in 1997/8 from the US (two ex-United States Air Force C-130B’s – 408 and 409 – and three ex-US Navy C-130F’s – 410 to 412 as part of their Excess Defence Articles programme. The two ex-US C-130B ‘s and a C-130F (411) were subsequently put in service, but the C-130F was retired soon thereafter.

Various modifications have been accomplished on the original SAAF aircraft, the most significant being a centre wing replacement and outer wing refurbishment from 1969 to 1972 done under the auspices of Lockheed, an engine upgrade (from Allison T56-A-7 to T56-A-15) during the early 1970s and a basic avionic upgrade during the early 1980s.

The two ex-USAF C-130B’s had already been modified with the fitment of H-model outer wings and a centre wing similar to that of the other SAAF aircraft. The fleet underwent a major refit from December 1996, when Marshall Aerospace of Cambridge in the UK and Denel was contracted to upgrade the aircraft as part of Project Ebb, fitting inter alia digital avionics in the place of the electromechanical. The upgrade was not without delay and infighting between Marshalls and Denel and ran seven years past its expected date of completion, set for June 2002: the project wrapped up as late as July 2009.

Aircraft 402’s brakes caught fire during a landing after a test flight in early 2005 at the then-Johannesburg International Airport. Damage estimated in the millions of rand was inflicted on the aircraft and an equally damaging dispute then erupted between Denel and Marshalls as to whom had to carry the cost of the repairs. It remains unclear why the taxpayer paid the R6 579 134 for the repair as well as a further R3 686 241.08 for hangarage at Denel Aviation before and during the repair. Another aircraft was also damaged while undergoing testing after upgrading – its fuel tanks were over-pressurised.

Seven of the nine were grounded in 2005 on the recommendation of the manufacturer after metal fatigue was discovered on the main spars and outer wing structures of several US C130Bs. As part of this the outer wings of aircraft 407 were removed. Lockheed Martin subsequently allowed three aircraft to resume flying, but in May 2006 the remaining four underwent a further battery of tests.
