I think the 20 TWC would be the least of your worries! I'd be more concerned with the 800m viz and +TS/CB overhead the field. Why would you even go near it let alone try an approach in it? Think of the down draught.

I know it's easy to sit and pontificate after the event but from what we know so far, on the face of it, this seems to be yet another accident caused by commencing an approach in totally inappropriate weather.....how many more?

Trans Asia accident record
 

According to Aviation Safety Net, this is the airline's first fatal accident with this aircraft type in which passengers have been killed. Two previous crashes - a positioning flight in 1995 and a freight service in 2002 - involved only crew casualties.

Based on the horrible photos in this link, I'm astounded that anyone survived.

Taiwan?s TransAsia Air Crashes at Penghu, 48 Fatalities - Bloomberg

ROC Air Force denies any role in GE222 crash - The China Post


ROC Air Force denies any role in GE222 crash

TAIPEI, Taiwan -- The R.O.C. Air Force yesterday refuted a local media report that alleged the Air Force could be responsible for a civilian airplane crash last week on the offshore island of Penghu.

TransAsia Flight GE222, which took off from Kaohsiung on the evening of July 23, crashed in Penghu, killing 48 of the 58 people on board.

The Chinese-language Next Magazine yesterday quoted a source as saying that the military could be partially responsible for the tragedy.

According to the magazine, the pilot of the aircraft, Lee Yi-liang (李義良), who was also killed in the accident, had previously asked the control tower of the Magong Airport if his plane could land on runway 2 instead of runway 20, due to the low visibility in the airspace near the airport.

The control tower of the joint military/civilian-use airport later asked the Air Force if the GE222 could land on the number 2 runway that is mostly used by military aircraft instead of civilian ones, the magazine said.

The number 2 runway is equipped with an Instrument Landing System (ILS), an internationally normalized system for navigation of aircraft on final approach for landing. With the ILS, it may be safer to land, the magazine said.

However, the military refused the request, ultimately leading to the crash of the airplane, the magazine claimed.

In response, the Air Force yesterday refuted the report, while expressing sincere protest over the “ungrounded accusation” the magazine raised.

The Air Force stressed the military had transferred jurisdiction over the Magong Airport to the Civil Aeronautics Administration (CAA, 民航局) as early as January 2001.

The CAA is now responsible for the control tower of the airport, it said in a released statement.

Also, all the fighter jets at the Magong air base were grounded on July 23 due to the stormy weather in the wake of Typhoon Matmo.

The control tower of the Magong Airport had full control over the landing and taking-off of all aircraft on that day, it noted.

The Air Force did not intervene with the tower control, it added.

The Air Force once again expressed regret over the tragedy. It added that the reason for the crash is now being investigated by the Aviation Safety Council (ASC).

CAA's Refutes Report

Meanwhile, the CAA yesterday also refuted the magazine report.

It confirmed that the pilot did ask the control tower to change to the number 2 runway before landing. According to regulations, the control tower needs to consult the Air Force before they approve or deny the request, according to the CAA.

However, the pilot later changed his mind and decided to try to land on runway 20 before the control tower could respond to his request, it said.

The CAA said it would not disclose more details about the accident because the investigation headed by ASC was still ongoing.



Wonder if this was a factor.

Pure conjecture: wonder if the attempt to land on 20 was due to not having enough fuel to wait for the conversation with the military.

And is there a cultural thing that equates declaring emergency with failure and humiliation, such that it's not done as often as in the West?

Yes. Absolutely there is.

News Release:

Aviation Safety Council

Good summary: ASN News » Report: Intentional descent below MDA in thunderstorm causes ATR-72 CFIT accident in Taiwan

Ouch:

8. According to the flight recorders data, non-compliance with standard operating procedures (SOPs) was a repeated practice during the occurrence flight. The crew’s recurring non-compliance with SOPs constituted an operating culture in which high risk practices were routine and considered normal.

First of two.
 

A very damning report indeed. Unfortunately I think the next report to come out for TNA 235 will be even more damaging.

Yes, but for whom?

Regrettably this sort of behaviour is common place at TransAsia. Contact approach's, Weather Radar approaches, ignoring all and any minimums etc etc. All with the inevitable and tragic consequences we have seen so often. Welcome to Taiwan.....

Is Taiwan a particularly litigious country? If it is me thinks TransAsia have big problems ahead.
