## Where they differ

- The Cessna 170B fleet is younger: half of those registered were built by 1953, against 1946 for the Cessna 140.
- Most Cessna 140s have the Continental C85; most Cessna 170Bs the Continental C145.
- The Cessna 170B carries more airframe ADs with a repeat action, 1 against 0: inspections that come back for as long as the AD applies.
- Mechanics report the Cessna 140's engine (reciprocating) most, and the Cessna 170B's reciprocating engine cylinder section.
