92 | AOPA PILOT August 2018

The Continental O-470, TSIO-520 and
TSIO-550 type certificates were issued
in 1952, 1956, and 1980, respectively. The
Lycoming IO-360 was certified in 1960 as
a fuel-injected variant of the carbureted
O-360 certified in 1955. It's hard not to
wonder why these Jurassic engines are
still being manufactured and installed in
new-production aircraft, instead of basking proudly in some aviation museum
next to the Curtiss OX-5, Le Rhône rotary,
Warner-Scarab, and Wright Whirlwind.
The reason, of course, is that the cost
and effort involved in certifying a new
aircraft engine design is so daunting that
only companies with seriously deep pockets can consider it. Even among those
deep-pocket companies, the track record
for innovation is dismal.

VIKTOR KOEN

POWERED BY OPTIONS

WHILE WORKING on my second book,
Mike Busch on Engines, I couldn't help
but reflect on what has changed in the 50
years since I bought my first airplane-and
what has stayed the same.
The engines themselves haven't
changed much. The Continental TSIO550-K that powers the new-production
Cirrus SR22T is not much different from
the Continental TSIO-520-BBs that power
my 1979 Cessna Turbo 310, and those
are second cousins to the Continental
O-470-R that powered my first airplane,
a 1968 Cessna 182 Skylane. The Lycoming
IO-360-M1A that powers the new-production Diamond DA40 XLS is nearly
indistinguishable from the Lycoming
IO-360-A1B6 in the 1971 Cessna 177RG
Cardinal.
