2 airmen killed in jet crash
By Jung Sung-ki
Staff reporter
Two crewmembers of an F-5F fighter jet were killed Friday as the aging jet crashed into waters off the country’s west coast during a routine training mission.
The Air Force immediately suspended operations of its fleet of F-5.
It was the second accident involving the F-5 in three months. In March, two F-5 aircraft plunged into a mountain in the eastern part of Gangwon Province. Three pilots were killed in the crash.
The F-5E aircraft took off from an airbase in Gangneung at around 9:43 a.m. for an air-to-ground strike mission and was returning to base, according to an Air Force spokesman.
The jet disappeared from radar screens at around 10:33 a.m., he said.
Search-and-rescue helicopters later found the bodies of the two pilots. The helicopters continued searching for debris, said the spokesman.
The South Korean Air Force introduced the F-5 about 30 years ago.
There are plans to replace the aging fleet of F-5 and F-4 fighter jets with up-to-date F-15K fighters.
Earlier this month, the Air Force decommissioned a fleet of 60 F-4D aircraft.

Fighter plane crashes underline need for accident prevention
Most of the F-5 fighters have surpassed their 30-year lifetime, but have remained active to deter N.Korea
» The wreckage of the South Korean F-5F fighter jet that plunged into the East Sea last Friday was salvaged by the Korean Navy, June 19. ¡¡
The Friday crash of an Air Force F-5F fighter plane into the East Sea brings the total of fighter accidents since 2000 up to 20, with 24 aircrafts lost. This means an average of two crashes take place every year. During the past ten years, the equivalent of one fighter plane squadron, which consists of around twenty aircraft, has disappeared in peacetime accidents.
The Air Force F-5 fighter in particular has earned an accident-prone reputation, as ten have crashed since 2000. On March 2, an F-5E and F-5F crashed in Pyeongchang, Gangwon Province. Now, three months later, another accident has occurred with the same model.
As a reason for the conspicuous frequency of F-5 accidents, military authorities have cited the fact that it is an old model introduced between 24 and 36 years ago. This means that the F-5s are at or past the end of their 30-year lifespan.
Military authorities explain that the reason the F-5 fighters have not been retired is because they are needed to maintain a deterrent against North Korea. Indeed, the roughly 170 planes of this model account for 35 percent of the Air Force¡¯s entire fighter plane fleet.
Because of this, the Air Force plans to use these fighters through the latter part of the 2010s, carrying out performance improvement efforts, rather than retiring them all at once.
In 2001, the Ministry of National Defense set as a national project the Korean-model KTX stealth fighter to replace fighter planes that had passed their retirement date, including the F-5 and F-4. However, the project has been delayed due to budget and technology issues. ¡°It is difficult to obtain parts for the F-5, so the parts have been secured by taking parts from the same model of fighter and attaching them to others,¡± explained a military official.
However, the recent string of crashes among similar types of Air Force fighters has led observers to question whether military authorities have taken too passive of an approach to accident prevention and dwelling excessively on budget issues.
Military authorities said there appeared to be no airframe damage to the fighter that crashed on Friday. But if it is discovered that the accident resulted from human error, such as poor maintenance, those authorities will have a hard time dodging criticisms.
Experts noted the need for active efforts by military authorities to establish accident prevention measures, given the loss of life, economic damages and security burden caused by the fighter crashes.
Based on accounts from the Air Force, it costs 9 billion Won ($7.6 million) over ten years to train KF-16 pilots, around 4.2 billion Won to train F-5 pilots, and around 7.5 billion Won for the F-4 model. Totaling all of the training expenses for the 20 pilots who have lost their lives over the past decade, taking into account the different models of plane, results in an overall 105 billion Won.
Factoring the cost of the planes themselves into the equation gives a loss of more than 560 billion Won. With an increase trend of experienced pilots moving into civil aviation, observers have begun to call for special accident prevention measures.
