From the Wikipedia article

1931 Jinan Air Crash occurred on November 19, 1931, when a Stinson Detroiter mail plane carrying one passenger and two pilots crashed into a mountainous area in Jinan, Shandong Province, China. All three people on board, including the only passenger, Chinese poet Xu Zhimo, died in the crash.

The aircraft was operated by China Airways Federal in the Republic of China and was contracted by Chunghwa Post. It departed from Ming Gugong Airport in Nanjing, heading to Nanyuan Airport in Beiping (now Beijing). The passenger, Xu Zhimo, was intending to attend an architectural lecture given by the well-known architect Lin Huiyin in Beiping. Because of Xu's fame as a poet, the crash shocked the literary community in China.

Crash

The Stinson Detroiter took off around 8:00 am local time. It cruised over the path of the Jing Pu Railway, which directed the flight to Beiping. The weather was fine during the first part of the flight. The plane landed at Xu Zhou Airport for refueling near 10:00 am, and took off again 10 minutes later. Captain Wang handed the controls over to first officer Liang, and moved to the passenger's seat. It then flew into Jinan airspace. The aircraft encountered severe fog and began flying off course. The pilot lost the railway in his sight, so he kept on heading for the nearby Wujiapu Airport, which would help him go back on course again. However, the plane started to descend. After the plane passed the waypoint in Changqing District, the pilot headed to the northwest for the target airport. Seconds later, the aircraft hit the peak of what is now called West Mountain below the summit, about six kilometers from Dangjiazhuang Railway Station, and broke off its right wing. This put the plane into a rapidly descending spiral, despite the fuselage remaining relatively intact. The Detroiter crashed into the valley below and disintegrated, resulting in a series of fire and explosions, killing two of the three on board instantly.

Crash site

The exact location of where the Stinson Detroiter crashed was controversial. The Government of the Republic of China claimed that the aircraft crashed into Mount Beida, where they erected a tomb to commemorate Xu. Popular descriptions of the crash site include West Mountain, East Mountain, North Mountain (later research showed that the three names were for the same mountain), Mount Kai, and Mount Baima.

In 2013, investigators deduced the final location of the wreckage according to the documents in the archive. With the help of a modern electronic rangefinder, they followed the Jing Pu Railway from Dangjiazhuang Station six kilometers north to a village called Chaomidian, which is north of the crash site. Ranging 1 kilometer from the village, the investigator found the valley, which was identical to eyewitness descriptions.

The investigation established that the crash site of the Stinson Detroiter was at West Mountain, which is east of Changqing District in southwest Jinan and one kilometer from the railway, at an elevation of 150 meters.

Investigation and cause

Investigation

Investigators first identified a piece of the aircraft's right wing a few meters from the mountain peak. Previously that year, a Fokker F-10 had crashed in Kansas in the United States due to a structural failure of the aircraft's wing. Investigators suspected that this might be a similar case, but after scrutinizing the debris, the theory was ruled out.

Since the crash pre-dated black boxes, investigators could only search for clues at the crash scene or in eyewitness accounts. Witnesses reported that the plane was flying dangerously low and was circling in the air seconds before the crash, suggesting that the pilots had difficulty finding their route.

In addition, there were two pilots commanding the Detroiter, whose cockpit is designed only for one pilot. The first officer was likely in control at the time of the accident due to the positions of the bodies at the crash scene.

Investigators hypothesized that the pilot descended the aircraft beneath the minimum safety altitude while attempting to seek their target, Wujiapu airport. Visibility was low due to fog, and the crew could only use compass heading to navigate. After the plane flew past Dangjiazhuang Railway Station, the first officer lost sight of the railway due to poor visibility. The airport runway lights were blocked by the mountains surrounding Jinan, but the pilot may have believed that it was only blocked by thick fog. Thus, he continued descending until the plane crashed into the mountain. Modern aircraft today would avoid such a crash with a ground proximity warning system.

The investigators believed that lack of communication between the pilots also played a major role, suggesting that the accident could have been avoided if the captain, sitting in the passenger's seat, had reminded the pilot at control that the flight was dangerously close to the terrain.

Another theory suggests that both the pilots were disoriented and failed to realize the plane was descending slowly. Therefore, the pilot could not know his exact altitude, which led to the crash.

The investigation of the Jinan air crash revealed deficiencies in early aviation regulations. The crew should have canceled the flight due to the possibility of severe meteorologic conditions.
