I am looking for some accident related answers.
My question is, what kind of entries or documents must be in the logbook, after a helicopter had an accident and was substantially damaged during hovering (it rolled inverted before impact).
Shouldn´t there be a Form 337 or some kind of accident report and a return to service entry in the technical log book reporting that accident?
Or is this documented somewhere else?
The only TLB entry is about blade change.
Isn`t it also necessary to have the transmission inspected/changed, because it took the impact forces from the blades?
The situation you refer to as to what log entries should be made after an accident has been the biggest issue, I think, with the older Brantlys. First of all, you have to consider parts availability and whether or not you want to trust the yellow tags on some of the components. Next, you must consider whether or not the person performing the overhaul and rebuild is competent to do the job and most importantly, if they are manufacturing parts to finish the rebuild, that are Brantly specific, do they have a PMA. If the IA/AP doing the rebuild is thorough, you should have a ton of small write ups or one huge write up listing what damage was found, what was done to repair the damage, what parts were replaced to repair the damage denoting serial numbers and service time remaining if applicable, one entry stating that a post maintenance ground run was accomplished, and an entry stating that a post maintenance flight was conducted and that the aircraft was returned to service. Most certainly there will be a form 337 when there has been a major repair. I found this at the FAA web site and felt that it needed to be pasted here.
"The FAA Form 337 is required anytime you have performed a MAJOR REPAIR and/or MAJOR ALTERATION. If you are not sure whether the maintenance that is being performed will be considered a Major Repair/Alteration, look at Appendix A of FAR Part 43 and the definitions of Major Repair/Alteration in FAR Part 1. (Also see question #2, How is a major alteration determined?)
A common misconception is that FAA Form 337 replaces the required maintenance record entry. This is not true. FAA Form 337 does not replace the maintenance record entry required by FAR Part 43. The last paragraph of Section 43.9(a)(4) states "In addition to the entry required by this paragraph, major repairs and major alterations shall be entered on a form, and the form disposed of, in the manner prescribed in appendix B, by the person performing the work." So, according to the regulations, a maintenance record entry is required even after performing a major repair or major alteration.
Another misconception is that a work order can be used in place of FAA Form 337. According to FAR Part 43, Appendix B, FAA certificated repair stations may use their work order in place of FAA Form 337 for major repairs only.
If you have any questions concerning FAA Form 337, contact your local FSDO"
I hope that this answers your questions and please be very diligent when researching the records of any aircraft that you are thinking about purchasing. If you don't feel you are qualified to do this research, there are people that can do this for you. I recomend to get a trusted IA that has helicopter experience, not necessarily Brantly experience, to research the log books for time life components, AD's, service bulletins as well as verifying serial numbers match on all components. It is my opinion that there are numerous "bastard Brantlys" in the air today because parts production ceased for so many years and people were still wanting to fly the outstanding machine and make a buck. Lastly, don't buy anything you wouldn't feel safe flying in
