Summarize Red Items

Factors That Could Have Led to Abnormality

Most Probable Factor

Possible Fixes

Factors That Could Have Led to Abnormality

Most Probable Factor

Possible Fixes

 Timelines

  • Poor delegation

  • Hesitancy to cancel flight test (and follow through on checkpoints)

  • Have regular sync up meetings and ensure deadlines are being met

Harnessing + Clearance

  • No proper guideline and strategy set for people harnessing to follow

  • Create guidelines for harnessing

  • Setup strict limitations for clearance from props and wires

Motor mounting + clearance

 

  • Different style used for mounting front motor

  • Use loctite

  • Take into consideration flexing

  • Ensure motor mounts are designed and validated to frame spec

Pixhawk mounting + Nose droop

  • Mounted on foam

  • Nose cone was developed for old cabin, which wasn’t manufactured as such

  • Use wood or metal instead that is firmly mounted

  • Redo nose cone

  • Ideally redo cabin in the medium term
