Results

  • Didn’t destroy the airframe

  • Followed checklist and brought required items

  • Good population of people

  • Timelines were generally relatively accurately followed

  • Communication on the flight line were slightly poor

  • Test CFG before getting to the flight line

  • Create checklist for spare PWM cables, wires, etc. in general

  • Ensure that spare parts that are brought are able to actually be used

  • Improve communication on the way to the flight test for prepping the aircraft

  • Communicate timelines properly beforehand on action items and following up prepping for flight tests, making sure that tasks are assigned

  • Harnessing for the aircraft needs to be addressed, ensuring clearance with motors

  • Delegate tasks in a manner that takes into account the bandwidth of each individual person

  • Set tighter checkpoints on timelines and making sure that if tasks aren’t completed, we cancel the flight test

  •  

  • RCA items to discuss:

    • harnessing

    • motor mounts

    • soldering

    • people factor

    •  

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

Action Items

Make sure we have timeline syncs for Icarus and flight tests (weekly)
Write guidelines for harnessing properly
@Hamza Ali @Alison Thompson @Nathan Green to own RCA, due EOD Tuesday
Update motor mounting to take into account the design of the frosted flakes airframe
Threadlock motors
Add minimum clearance between any moving parts and wires/harnessing, airframe, electronics
Update PDB used
Redo suboptimal solder joints
