Last update from Bombardier TechSupport and Safety Team - fuel tank wire meggering allowed and safe if fuel tanks are drained and vented. I'm srill having my doubts here, so I'll stay with the TDR just to be on the safe side.
Thank you all for your valuable input. Issued was finally fixed consulting AMM (Fuel Tank - no tools/testing/measuring equipment batterry/electric powered that can initiate a spark), also acquired a TDR as per WDM Standard Practices.
Thank you all for your reply. Here is the situation: what's the best way to check a wire connection to a fuel probe, in a drained/ vented fuel tank (Bombardier CRJ 100/200/705)? Fuel probe was tested OK, but apparently the connecting wires were at fault. FIM recommended wire check by meggering...
Thank you TZ350 for your reply. I'll sure look into it. What I've learned from different sources/some FSRs (field service reps. from few aircraft manufacturers)is that there is no fixed value for the magnetization (gauss); some of them recommends 4-5 gauss for MLG/NLG as acceptable. But...
Does anyone knows what will be an acceptable level of magnetization (how many Gauss) for aircraft/ aircraft components (landing gear, etc) magnetization after a lightning strike occurrence (plane hit by a lightning strike)? I am looking specifically for Bombardier's CRJ705, but any other...
