250 KIAS SPEED RESTRICTION

[Thomas J. Hammond]

A Canadair RJ-200 pilot reported a 250 KIAS speed restriction due to
structural reasons.

Can anyone provide more detailed info on the RJ-200 problem???

In the old Boeings, we had a similiar restriction if the windshield
heat was inop. Bird proofing.

Sounds fishy. If there were a structural problem that required slower
speeds, I would think the FAA would ground the fleet. And, who would
fly them anyway with such a limitation?

Not fishy at all. See my previous post about the windshield heat system.

In addition, I flew the L-188 Lockheed Electra for a couple of years
with an FAA mandated speed restriction due to the wings falling off.

They didn't ground the Bonanzas when they issued the very restrictive
speed limit on them. 250K**I**AS doesn't sound like much of a
limitation though. That's pretty darn fast at Jet altitudes.

Huh? What does windshield heat have to do with birds?

The colder the windshield is, the more brittle it is.

The windshield or the pilots?

When the wings on the King Airs were falling off they didn't issue a speed
restriction. However, all the bolts have to be changed now at 5 years and
the bathtub fittings inspected. The later models have the wing bolts in
shear rather than tension. Too bad the theory was "safe life" rather than
"fail safe." But that WAS how most airplanes were built.

As another poster said, it could have been due to a windshield crack. (BTW,
on a 727 there is no restriction if an outer pane only is cracked. A
pressurization limitation of 5PSID and 2 PSID would be imposed in the event
of inner or both panes cracked, respectively).

Another reason for a speed limitation (on the B727) include inop Yaw Dampers
(270K to 350K depending on altitude)

It's not necessarily a fleetwide problem, it could be just that airplane.

Windshield heat probably has something to do with windshield strength.

Supposedly, a bird striking a warm windshield will bounce off rather than
breaking though. I'm sceptical of that myself, but I expect that the bird
doesn't care either way.

Indication problem with the gear most likely. Flew with it down and pinned.
Most other problems can be speed taped and flown at normal speed.

What is "speed taped"?

Aluminum tape with a strong adhesive. Great Stuff. The stuff we used was
rated for 500 MPH. Used to cover dents or holes in composite parts.

Can I use it on our cherokee to go 500 mph?

Michelle, et al,

Along similar lines, I recently flew an America West 757 that had it's
spoilers placarded as INOP and according to the Captain, per their MEL they
were altitude restricted to no higher than FL290...

RVSM starts at 290 doesn't it? Why would spoilers (or the lack of same) be
a concern for RVSM flight?

Just wondering if anyone may have a clue on this...

Yes. Use the speed tape to attach a turbofan engine to it.

[Michelle P]

Time to descend to 14000 in the event of loss of cabin pressure. No
Spoilers takes longer and therefore has to fly at a lower altitude.

Maybe if you tape on a JATO pack! ;)

The analogy used when I was taught this was to consider the nature of
toffee; warm toffee bends and will rarely shatter if dropped, toffee from
the fridge shatters with minimal impact. Same deal with the glass and
laminates in the windshield.
