Living Vicariously—and Safely

"That’s what I would have seen if I had followed Jim’s suggestion to look directly into the throttle body." Philippe DeKemmeter

Key Takeaways:

  • The author encountered an unexpected engine runaway at high power due to a slipping throttle butterfly shaft, a problem quickly diagnosed and fixed by a mechanic after initial misdiagnosis.
  • He reflected on having ignored subtle, preceding symptoms (throttle lag) for months, rationalizing them away, highlighting a human tendency to avoid confronting ambiguous problems.
  • The incident demonstrated the value of vicarious learning, as a friend's past story about a similar throttle issue allowed the author to react immediately and calmly by using the mixture control.
  • This personal experience underscored the purpose of his "Aftermath" column: to provide pilots with vicarious knowledge from others' incidents to help them make safer decisions in potentially dangerous situations.

Santa Paula Airport is a 20-minute flight from my home base, Whiteman Airport. The fuel there is $1.25 per gallon cheaper, however, so when I’m flying around the local area, I often stop at Santa Paula to refuel. The precise economics of fuel tourism are an SAT-level problem, but if I’m over Santa Paula anyway, I figure the extra landing and takeoff can’t cost me more than 10 bucks.
