Episode notes
Certification Creates Decades-Long Aftermarket
- Once a part is certified for a specific aircraft, that supplier effectively owns the part for decades due to certification rules.
- Airplanes fly 30–50 years on average, creating long aftermarket tails and predictable recurring revenue.
Pricing To Value, Not Cost
- TransDigm prices to perceived value and switching cost rather than to cost, often raising prices after acquisition.
- The DoD found TransDigm charged more than 'fair and reasonable' margins on almost all reviewed contracts, highlighting friction with regulators.
Tiny Part, Huge Margin Example
- Daniel shares that many TransDigm parts have absurd margins because they are tiny relative to aircraft cost and often ignored by OEMs.
- His father at Airbus said parts under ~$800 get reordered without a refund process due to low administrative cost.
