== ASX Accident Report ==
On May 14, 2025, at approximately 15:00 local time, a Japan Air Self-Defense Force Kawasaki T-4 training aircraft, tail number 96-5625 and assigned to Nyutabaru Air Base, crashed into Iruka Pond in Inuyama City, Aichi Prefecture. The aircraft had departed from Komaki Air Base shortly before the incident. According to defense officials, the T-4 disappeared from radar two minutes after takeoff. The flight was a return leg after a maintenance ferry mission involving an F-15 fighter jet. The two crewmembers onboard were a highly experienced captain who had piloted the F-15 earlier that day and a first lieutenant assigned to the T-4.
On the morning of Saturday, May 17, 2025, a Beechcraft 95-B55 Baron, registration N4321Z, departed from Rocky Mountain Metropolitan Airport (KBJC) in Broomfield, Colorado. The aircraft, owned and operated by CEDOCS, was a privately operated 1972 twin-engine model with two occupants on board. Approximately three minutes after takeoff from runway 30R, at around 10:03 a.m. local time, the aircraft climbed to an estimated altitude of 300 feet above ground level before initiating a right-hand descending turn. This maneuver occurred shortly after the pilot made a radio transmission indicating the need to return to the airport due to an onboard issue.


Witnesses near Iruka Pond reported hearing a loud noise followed by emergency vehicle sirens, with some reporting visual confirmation of the aircraft entering the water. Emergency services were dispatched quickly, and fragments of the aircraft were soon recovered from the pond’s northwest section. Additionally, lifesaving equipment, helmets, and uniform items believed to belong to the crewmembers were found floating on the surface. Divers and search teams continued operations into the evening, although the aircraft itself was presumed to have sunk.
Air traffic control recordings captured the pilot’s transmission stating, “We're going to have to go back and re-land. We've got the door popped open... we can hardly hear you, sir.” The tower immediately cleared the aircraft to return and land on any available runway. No further communication was received from the aircraft after that point. Witnesses and radar tracking confirmed that the aircraft lost altitude quickly and impacted a field east of Brainard Road, just north of U.S. Route 36, in the vicinity of the Carolyn Holmberg Preserve.


Weather conditions at the time of the crash were not reported as severe, and no adverse meteorological factors have yet been identified. The T-4 aircraft involved was a 36-year-old platform with no flight data recorder or cockpit voice recorder installed, which presents complications for accident investigators. While the Japan Ministry of Defense has not yet confirmed the cause, they have acknowledged the absence of mechanical distress calls or warning indicators from the crew before radar contact was lost.
Emergency services were dispatched immediately following the radio call and subsequent disappearance of the aircraft from radar. Upon arrival, responders found the aircraft on fire and were able to extinguish the blaze rapidly. The crash resulted in the complete destruction of the airframe and the deaths of both individuals on board. The National Transportation Safety Board (NTSB) and the Federal Aviation Administration (FAA) began an investigation into the cause of the crash, and the site was secured for further examination. Data from ADS-B tracking and communications were preserved for analysis.


In response to the crash, the Japan Air Self-Defense Force grounded nearly 200 Kawasaki T-4 aircraft nationwide pending a thorough review of maintenance records and flight safety protocols. The aircraft, introduced in the late 1980s, has served extensively as a jet trainer for JASDF pilot development programs. The Ministry of Defense emphasized the need for cautious and comprehensive checks before resuming flight operations to ensure no systemic failure contributed to the incident.
Preliminary findings suggest that the emergency originated from a mechanical issue involving the cabin door, which may have compromised cockpit communication or flight stability during a critical phase of flight. However, no conclusions regarding the root cause of the crash have been released pending full investigation results. The flight did not have a specified destination, and the nature of the flight was personal or private in purpose. Investigative teams continue to review physical wreckage, maintenance history, and pilot records to determine the underlying factors leading to the loss of control shortly after takeoff.
 
The search continues for the missing crewmembers, although the discovery of helmet fragments and other personal gear increases concern about survivability. Investigations remain underway, involving the Self-Defense Forces, local law enforcement, and aviation safety officials. Recovery operations are focused on extracting the submerged fuselage and collecting environmental samples due to observed fuel leakage in the water.

== Flight Tracking ==
Upon reviewing the available data from Flightradar24, FlightAware, ADS-B Exchange, and AirNav Radar, there is no publicly accessible flight tracking information for the Japan Air Self-Defense Force (JASDF) Kawasaki T-4 aircraft, tail number 96-5625, involved in the May 14, 2025, crash near Iruka Pond in Inuyama City, Aichi Prefecture. This absence is consistent with the operational characteristics of military aircraft, which often do not broadcast ADS-B signals or have their transponder data publicly available due to security protocols.
The lack of flight data is further compounded by the aircraft's equipment; the T-4 in question was not fitted with a flight data recorder or cockpit voice recorder. This omission presents significant challenges for investigators attempting to reconstruct the flight path and determine the sequence of events leading to the crash. As a result, the investigation relies heavily on physical evidence recovered from the crash site, eyewitness accounts, and maintenance records.
The Japan Ministry of Defense has confirmed the recovery of various aircraft fragments, including parts of the fuselage and pilot equipment, from Iruka Pond. Additionally, fuel leakage has been observed in the water, prompting environmental concerns and necessitating containment measures. The search for the missing crew members continues, with efforts focused on underwater recovery operations and analysis of the recovered debris.
In response to the incident, the JASDF has grounded nearly 200 T-4 aircraft nationwide to conduct thorough safety inspections and review operational protocols. This precautionary measure aims to ensure the airworthiness of the fleet and prevent similar occurrences in the future. The T-4, introduced in 1988, has been a staple in JASDF pilot training programs, and this incident marks a significant moment in its operational history.
The investigation remains ongoing, with multiple agencies collaborating to ascertain the cause of the crash. Given the absence of flight data and the challenges associated with underwater recovery, the process is expected to be meticulous and time-consuming. Findings from this investigation will be crucial in informing future training and maintenance practices within the JASDF.

On the morning of Saturday, May 17, 2025, a Beechcraft 95-B55 Baron, registration N4321Z, departed from Rocky Mountain Metropolitan Airport (KBJC) in Broomfield, Colorado. The aircraft, owned and operated by CEDOCS, was a privately operated 1972 twin-engine model with two occupants on board. Approximately three minutes after takeoff from runway 30R, at around 10:03 a.m. local time, the aircraft climbed to an estimated altitude of 300 feet above ground level before initiating a right-hand descending turn. This maneuver occurred shortly after the pilot made a radio transmission indicating the need to return to the airport due to an onboard issue.

Air traffic control recordings captured the pilot’s transmission stating, “We're going to have to go back and re-land. We've got the door popped open... we can hardly hear you, sir.” The tower immediately cleared the aircraft to return and land on any available runway. No further communication was received from the aircraft after that point. Witnesses and radar tracking confirmed that the aircraft lost altitude quickly and impacted a field east of Brainard Road, just north of U.S. Route 36, in the vicinity of the Carolyn Holmberg Preserve.

Emergency services were dispatched immediately following the radio call and subsequent disappearance of the aircraft from radar. Upon arrival, responders found the aircraft on fire and were able to extinguish the blaze rapidly. The crash resulted in the complete destruction of the airframe and the deaths of both individuals on board. The National Transportation Safety Board (NTSB) and the Federal Aviation Administration (FAA) began an investigation into the cause of the crash, and the site was secured for further examination.
