Investigation Summary
The flight was a contracted mail service for Chunghwa Post, also carrying the poet Xu Zhimo as a passenger. After a refueling stop at Xuzhou, the crew encountered deteriorating weather conditions near Jinan. The Stinson Detroiter, which featured a cockpit designed for a single pilot, was being operated by the First Officer while the Captain occupied the passenger seat. Investigators concluded that the crew attempted to navigate through thick fog using only a compass and visual landmarks. When they lost sight of the railway line, they likely descended in an attempt to break out of the clouds or locate the runway lights of Wujiapu Airport. The aircraft's right wing struck the summit of West Mountain at an elevation of approximately 150 meters, sending the plane into a spiral. The subsequent crash into the valley resulted in a fire and explosions. Although the First Officer was found alive by rescuers, he succumbed to his injuries during transport to the hospital.
Final Conclusions
The investigation attributed the accident to Controlled Flight Into Terrain (CFIT) caused by poor visibility and pilot disorientation. Contributing factors included the crew's decision to continue the flight despite warnings of uncertain weather, the lack of modern navigational aids, and poor cockpit communication, as the Captain was not in a position to effectively monitor the First Officer's flight path. The crash highlighted significant deficiencies in early aviation regulations regarding flight cancellations due to meteorological conditions.

Systems & Failure Modes
Visual Navigation
The crew relied on following the Jing Pu Railway as a primary navigational reference, a common practice in early aviation that failed when visibility dropped.
Cockpit Layout
The Stinson Detroiter SM-1F cockpit was designed for one pilot; having two pilots required one to sit in the passenger cabin, hindering effective Crew Resource Management (CRM).
Interesting Facts

- 05The First Officer was the only occupant found alive at the scene, but he died en route to the hospital.
Safety Actions & Advisories
Aviation Regulation Reform
The investigation identified a need for stricter regulations regarding flight cancellations during severe meteorological conditions.
Known Controversies & Unanswered Questions
Crash Site Location
Reference ↗For many years, the Republic of China government officially identified Mount Beida as the crash site and erected a tomb there, though 2013 research confirmed the wreckage was actually at West Mountain.
Sabotage Allegations
Reference ↗Conspiracy theories suggested the plane was targeted by special agents due to Xu Zhimo's romantic rivalries or political coincidences, though no evidence supported these claims over the official CFIT finding.
