Piper Seneca II vs Cessna 310

Check into the spar issues with the Cessna 3xx (not 377 which has its own
issues), 4xx line, and its off and on and off again SB/AD that can
potentially doom the fleets value...


AvWeb had it maybe a month ago. Found it ...

FAA Issues Final Cessna Wing Spar ADs

By Mary Grady

After much back and forth between the FAA and owners of affected Cessna
twins, two final Airworthiness Directives about wing spars were issued last
week. The final ADs require a spar-strap modification, but allow most owners
up to 800 flight hours to comply -- that's four to eight years of flying for
most owner-operators. The modification then is good for another 5,500 to
12,000 hours, with no further inspections required. The initial cost to
comply is still high -- aviation columnist Mike Busch told AVweb he
estimates it will cost $40,000 to $60,000 per airplane, and up to two months
of downtime. However, he said, the market value of Cessna 300/400 twins
should start increasing now that the AD is on the streets. "It has long been
my feeling that the uncertainty of the impending rulemaking was depressing
the market more than the certainty of a known AD," Busch said. "Furthermore,
the spar-strap mod will instantly increase the market value of the aircraft
by very nearly 100 percent of the cost of the modification, so the
modification cost will largely be recaptured if and when the aircraft is
sold."
