Navy's first 10,000-hour accident-free helicopter pilot: Instructor Park Ki-hyun's 34 years guarding the sea

Open ocean with no visual reference points. Sea fog rolling in without warning. Low-altitude, low-speed flight skimming less than 500 feet (about 150 meters) above the water's surface.

A Navy pilot has now logged 10,000 hours in those conditions — the most demanding in helicopter aviation — without a single accident. It is a first in the service's history.

The Navy announced Sunday that Park Ki-hyun, a flight instructor at the Naval Aviation Command's 609th Education and Training Wing, achieved 10,000 accident-free flight hours during a training sortie on Thursday. It took 34 years from his first mission as a Navy helicopter pilot in 1992.

Ten thousand hours is nearly three years and five months of continuous flying at eight hours a day. Maritime helicopter operations are far more demanding than overland flight: without terrain features for reference, pilots must judge altitude and attitude by instruments alone, and weather conditions can shift rapidly. The mission profile — extended flight at low altitude (below 500 feet) and low speed (below 60 knots) — leaves little margin for error. That is what makes the record so significant.

Park's connection to the Navy traces back to his father. A native of Pohang, North Gyeongsang Province, he grew up watching his father serve 27 years in the Marine Corps, including as a command sergeant major of a tank battalion, and set his sights early on a career as a Navy or Marine officer. After graduating from Korea Aerospace University with a degree in aviation operations, he was commissioned as a Navy ensign in June 1991 (Officer Candidate School Class 84) and spent the next 19 and a half years flying operational missions over the sea as an active-duty helicopter pilot.

When he retired as a lieutenant commander in 2010, he did not put down the controls. The following year he returned as a civilian flight instructor with the Naval Aviation Command's flight training battalion, and over the next 15 years trained 378 helicopter pilots — 347 from the Navy, 28 from the Marine Corps and three from the Air Force.

Park has flown six helicopter types. He made his first flight in the OH-23GT training helicopter as a student pilot, then progressed through the 500-MD light armed helicopter, the Alouette III (ALT-III) maritime operations helicopter, and the UH-60 and UH-1H utility helicopters. He now teaches the next generation on the Bell 505 trainer.

Above all else, Park puts flight safety first. Through constant refinement of his airmanship and technical knowledge, he was named the Naval Aviation Command's longest-flying instructor for three consecutive years from 2016 to 2018, and again in 2022.

"Behind the number 10,000 hours are the pilots who sweated alongside me every step of the way, and the countless comrades on the ground — air traffic controllers, maintenance crews and many others — who supported us while I tried to stick to the basics at every moment," Park said. "I will continue to do my utmost to train elite helicopter pilots who guard the sea from the sky."
