Aircraft Flight Operation Regulations Article 343
No person may operate a large aircraft or transport category aircraft unless it is equipped with a flight recorder. The recorders of which are capable of recording essential information of a flight and sufficient for investigation if aircraft involved in accident or incident. Specific specifications to the recorder shall comply with the international flight standards approved and adopted by CAA.The flight recorder shall be activated before flight, and shall not be deactivated in flight. However, in the case of an aircraft accident or aircraft serious incident, the flight recorder shall be deactivated when the flight ends, and shall not be re-activated until the flight data has been retrieved. This requirement shall apply to aircraft incident where CAA so requires.The following operation conditions shall be exempted from the restrictions as set out in paragraph 1 herein:1. Ferry an aircraft with an inoperative flight recorder from a place where repair or replacement cannot be made to a place where they can be made;2. Continue a flight as originally planned, if the flight recorder becomes inoperative after the aircraft has taken off;3. Conduct an airworthiness flight test during which the flight recorder or cockpit voice recorder is turned off to test it or to test any communications or electrical equipment installed in the aircraft; or4. Ferry a newly acquired aircraft from the place where possession of it is taken to a place where the flight recorder is to be installed.5. Flight with inoperative flight recorder, the following should be observed:a) For not more than 15 days while the flight recorder is inoperative and/or removed for repair provided that the aircraft maintenance records contain an entry that indicates the date of failure, and a placard is located in view of the pilot to show that the flight recorder or cockpit voice recorder is inoperative.b) For not more than an additional 15 days, a certificated person authorized to return an aircraft to service certifies in the aircraft maintenance records that additional time is required to complete repairs or obtain a replacement unit.
中文原文 航空器飛航作業管理規則第343條
航空器所有人或使用人應於大型航空器或運輸類飛機上裝置飛航紀錄器，始得飛航；該紀錄器應記錄供航空器失事調查使用之必要飛航資料，其詳細規範依民航局核定採用之國際飛航標準辦理。
飛航紀錄器應於飛航前開啟，不得於飛航中關閉。
但於航空器失事或航空器重大意外事件發生後，應於飛航中止時即關閉飛航紀錄器，於取出紀錄前，不得再開啟飛航紀錄器；其發生航空器意外事件經民航局要求者，亦同。
符合下列情形之一者，不受第一項之飛航限制：
一、將飛航紀錄器失效之航空器自無修理能力之地點運渡至有修理能力之地點。
二、飛航紀錄器於航空器起飛後失效，得繼續依原飛航計畫飛航。
三、執行適航試飛或測試該航空器裝置之通信或電子設備，需將飛航紀錄器關閉時。
四、運渡至裝置飛航紀錄器地點之飛航。
五、飛航紀錄器失效時，符合下列規定之飛航：
（一）當飛航紀錄器失效或拆除修理，應填寫維護紀錄，並將飛航紀錄器失效之標示牌置於駕駛員易見之處。
但自失效日期起不得超過十五日。
（二）如需更長時日完成維護或取得替換零件時，除符合前目規定外，經授權合格人員於維護紀錄簿中簽證，得延展不超過十五日。
