What Was The Problem

[pelmet]

Reminds me of a really bad nosewheel vibration one time on takeoff on a long flight but everything was fine on landing. I was sure there was a tire issue.

From TSB......

C-GLDE, an ATR 42-320 operated by Transwest Air (dba Rise Air), was conducting flight RS424
from Prince Albert/Glass Field Airport (CYPA), SK to Saskatoon/John G. Diefenbaker International
Airport (CYXE), SK. During the takeoff from CYPA, the aircraft experienced an aggressive yaw to
left at 90 knots. Control of the aircraft was maintained, and the aircraft rotated at 94 knots. The
crew elected to keep the landing gear extended; suspecting the yaw was caused by a blown tire.
The aircraft returned to CYPA and conducted a fly-by to determine the tire condition. Ground to air
visual inspection determined that there was no visible damage to the tire. The gear was left
extended, and the decision was made to continue the flight to CYXE. A PAN PAN was declared,
and aircraft rescue and fire fighting were on standby for the uneventful landing in CYXE. The
aircraft then taxied to apron without issue.
The operator's maintenance conducted various tests and no issues with the aircraft was identified.
The aircraft was returned to service and it has been reported the issue has not reoccurred.

The old adage, must of been a gust sir!
In case it’s not common knowledge, a good first officer must remember three things, “it must of been a gust, nice landing and I’ll take the ugly one”

the aircraft experienced an aggressive yaw to the left

Here’s something possibly worth to google … A Yak 42 accident on September 7 2011 was determined to be in part due to foot position on rudder pedal for takeoff. It took some reading to find the part again where a leg reflex (medical condition description in that report) is suggested to have caused inadvertent application of brakes on this “nominal power” takeoff. (An obvious visual of smoke on some crash footage or cam shows tailwind past the delayed V1/V2 location on slightly downslope runway).

You must not be a good first officer then, because you forgot rule #4, "I'll take the cheque".
