 First, there was no corrective action taken with regard to nickel cadmium batteries until after the Aloha Airlines Flight 845 accident on the runway in Honolulu that took place on August 8, 1971. The corrective action taken as a result of that accident was included in Airworthiness Directive 71-21-5 and Advisory Circular AC 00-33. These were superseded by Advisory Circular AC 00-33A, dated February 14, 1973. First, there was no corrective action taken with regard to nickel cadmium batteries until after the Aloha Airlines Flight 845 accident on the runway in Honolulu that took place on August 8, 1971.

 +Second, the information regarding Sonotone batteries that I have found in United Airlines and Capital Airlines flight manuals from the early 1960s do not mention dangers or risks involved with the use of Sonotone batteries in Vickers Viscount aircraft. In fact, it is my opinion that the Airworthiness Directives and Advisory Circulars directly ​ contradict the information provided in the aforementioned flight manuals and show how a false sense of security was made possible with regard to Sonotone batteries.
  
 **UPDATE:** Correction. [[FAA Order WP 6000.6 Ni-Cad Batteries 8/8/66|An ORDER from the FAA, dated, 8/8/66]] was issued with regard to nickel cadmium batteries. This bulletin included a discussion of tests performed on ni-cad batteries and methods used to charge them. Corrections via Airworthiness Directive 71-21-5 concerned the different types of battery cases that comprised Sonotone Batteries and their tendency to overheat, while the later Advisory Circulars were refinements of the FAA Order of 1966. **UPDATE:** Correction.
