At niagara falls, ny, kiag, runway 28L assigned for takeoff. The small aircraft aircraft has a propeller clearance of only 8 1/4 inchs. 28L crosses runway 6/24 approximately 1100 ft from the takeoff end of 28L. Runway 6/24 is crested with a topography so that the aircraft on it's takeoff roll on 28L as it cross 6/24 commences first a down roll, then up to the crest and down the other side, and then up to the level of 28L. The small aircraft aircraft had not quite reached flying speed when it commenced to cross the undulating 6/24 runway surface. The small aircraft aircraft takeoff was disturbed so that it first pitched up and then down, destroying the lift of the laminar flow wings. The aircraft started to porpoise which was controled after it reached the far side of the cross runway. The small aircraft aircraft propeller tips did not contact the runway, but they must have been mighty close. After turn out, the tower controller was advised of the forgoing experience. The controller responded 'oh yes, it has been like that for yrs.' he made no response to the pilot's suggestion that the controller should have advised the pilot of the condition, and offered an opportunity to use 28R as an alternate. 28R does not cross another runway. Traffic was very light at the time. When the tower controller was asked who should be advised that the condition was dangerous, he suggested a letter to the airport authority. He was advised that this report to ASRS would be made in the interest of flight safety. No far violations involved.

Title: PLT OF SMA PVT ACFT RPTS AN UNEVEN RWY INTXN CAUSING A ROUGH TKOF.
Narrative: AT NIAGARA FALLS, NY, KIAG, RWY 28L ASSIGNED FOR TKOF. THE SMA ACFT HAS A PROP CLRNC OF ONLY 8 1/4 INCHS. 28L CROSSES RWY 6/24 APPROX 1100 FT FROM THE TKOF END OF 28L. RWY 6/24 IS CRESTED WITH A TOPOGRAPHY SO THAT THE ACFT ON IT'S TKOF ROLL ON 28L AS IT CROSS 6/24 COMMENCES FIRST A DOWN ROLL, THEN UP TO THE CREST AND DOWN THE OTHER SIDE, AND THEN UP TO THE LEVEL OF 28L. THE SMA ACFT HAD NOT QUITE REACHED FLYING SPD WHEN IT COMMENCED TO CROSS THE UNDULATING 6/24 RWY SURFACE. THE SMA ACFT TKOF WAS DISTURBED SO THAT IT FIRST PITCHED UP AND THEN DOWN, DESTROYING THE LIFT OF THE LAMINAR FLOW WINGS. THE ACFT STARTED TO PORPOISE WHICH WAS CTLED AFTER IT REACHED THE FAR SIDE OF THE CROSS RWY. THE SMA ACFT PROP TIPS DID NOT CONTACT THE RWY, BUT THEY MUST HAVE BEEN MIGHTY CLOSE. AFTER TURN OUT, THE TWR CTLR WAS ADVISED OF THE FORGOING EXPERIENCE. THE CTLR RESPONDED 'OH YES, IT HAS BEEN LIKE THAT FOR YRS.' HE MADE NO RESPONSE TO THE PLT'S SUGGESTION THAT THE CTLR SHOULD HAVE ADVISED THE PLT OF THE CONDITION, AND OFFERED AN OPPORTUNITY TO USE 28R AS AN ALTERNATE. 28R DOES NOT CROSS ANOTHER RWY. TFC WAS VERY LIGHT AT THE TIME. WHEN THE TWR CTLR WAS ASKED WHO SHOULD BE ADVISED THAT THE CONDITION WAS DANGEROUS, HE SUGGESTED A LETTER TO THE ARPT AUTHORITY. HE WAS ADVISED THAT THIS RPT TO ASRS WOULD BE MADE IN THE INTEREST OF FLT SAFETY. NO FAR VIOLATIONS INVOLVED.
