HISTORY OF FLIGHT
On Monday, April 12, 1993, at about 0951 eastern daylight time, a Piper PA 32, N292SP, piloted by Robert Freeman, impacted trees in a wooded area, 10 miles south of the Cortland Chase Field, Cortland, New York. The airplane was destroyed. Both pilots and one passenger were fatally injured, and two passengers received minor injuries. Instrument meteorological conditions prevailed. An instrument flight plan had been filed for the flight operating under 14 CFR 91.
The purpose of the flight was to conduct instrument training for the non instrument rated pilot, Ethel Karp, by a certified flight instructor, Robert Freeman, while returning three college students to Cortland, New York.
The flight instructor called Bridgeport Automated Flight Service (AFS) at 1613 on April 11, 1993, for a weather forecast for the next day. The AFS informed Mr. Freeman that the aviation forecast was only through 7:00 A.M. on the morning of the 12th. The AFS then provided the following:
"... the outlook after 7:00 A.M. at Bradley field ...marginal V.F.R. due to the ceiling with rain drizzle and fog...Ithaca New York it says marginal V.F.R. due to the ceilings, at Binghamton it says I.F.R. after 7:00 A.M. due to fog, becoming V.F.R. by 10:00 A.M." the AFS the stated to Mr. Freeman, :...you know you best bet is to ah check back after 8:00 o'clock tonight..." Mr. Freeman stated that, "... After 8:00 I'll talk, I'll try it then..."
Approximately 2 hours later, at 1821, a computer weather briefing was requested and received, through the Direct User Access Terminal System (DUATS), for N292SP. At 2059, a second DUATS briefing was requested for N292SP.
A person contacted Bridgeport AFS, at 2131, and filed an instrument flight plan for N292SP. No weather was obtained during this telephone call.
On April 12, 1993, at 0754, N292SP was issued an instrument flight rules (IFR) clearance by Groton Air Traffic Control Tower to Cortland, New York, and at 0801, N292SP departed form the Groton Airport. N292SP was issued a climb to 6,000 feet and remained at that altitude until the initial descent into Cortland, New York.
According to pilot reports, the tops of the clouds in the Ithaca, New York area, were 4,000 feet. The two surviving passengers stated that the enroute flight was conducted over the cloud layers.
The pilot of N292SP made contact with Binghamton TRACON and asked, "...are you V.F.R. right there sir." The radar controller replied, "ah negative we're showing measured ceiling five hundred overcast visibility one zero." N292SP then inquired , "ok any idea what's going on up at Cortland." The radar controller said, "november two sierra papa you contact AWOS (Automated Surface Observing System), at Cortland, on one three two point two five. N292SP read back the frequency change."
The Cortland ASOS records reported an 800 foot overcast ceiling until 0901, then lowering to 600 foot overcast. The visibility remained at 10 miles for both reports.
0908:00: N292SP advised approach control, "ah two sierra pop ah looks like we're going to have to prepare for a miss over to ah Ithaca do you have Ithaca's weather." The controller requested N292SP to "standby," and he contacted Elmira Approach Control via telephone to obtain the Ithaca weather. At 0910:11, the controller transmitted, "ah two sierra papa Ithaca weather estimated ceiling one thousand overcast visibility seven temperature three one dew point two niner wind three five zero at one zero altimeter two niner eight niner." The controller advised N292SP, "and november tow sierra papa your cleared to the Ithaca Airport via present position direct Binghamton VOR direct Cortland maintain six thousand." N292SP acknowledged the clearance.
0921:19: the controller instructed N292SP,"...turn right heading three one zero vector final approach course V.O.R. alpha into Cortland." N292SP acknowledged the heading. At 09222:23, the controller transmitted to the flight crew of another airplane inbound to Binghamton, "...have moderate rime ice reports four thousand to three thousand on final runway three four also light to moderate mixed icing three thousand to two thousand on final reported by a Beech nineteen hundred."
After several transmissions between the controller and N292SP, the controller instructed, "november two sierra papa descend and maintain four thousand;" followed by: "...present position ah correction fly present heading join the final approach course V.O.R. alpha into Cortland." At 0930:38, the controller issued N292SP the approach clearance, which was acknowledged.
0932:20: the controller provided a USAir flight, the icing PIREPS that he had provided earlier.
0935:35: the controller advised N292SP, "...show you over IILEN now radar service terminated...freq change to advisory frequency approved." N292SP responded, "changing the frequency two sierra pop."
0939:28: N292SP transmitted, "Binghamton approach ah Saratoga two sierra pops on the miss ah heading for CORTA." The controller acknowledged N292Sp, and transmitted, "...your cleared to the Ithaca airport via radar vectors turn right heading two zero zero vector to final approach course Ithaca maintain four thousand." N292SP acknowledged the altitude and received further instructions from the controller to squawk a transponder code and ident. At 0943:25, the controller instructed, "...contact Elmira one two four point three good day." N292SP acknowledged the frequency change.
0943:43: N292SP transmitted, "Elmira approach this is nine two sierra papa ah with you four thousand." The controller responded, "...fly heading two one zero vector to the I.L.S. final approach course runway three two at Ithaca standby for the weather." N292SP acknowledged the heading and at 0945:30 transmitted, "Elmira two sierra pop picking up some problems some ice ah can we have lower." The radar controller said, "november two sierra papa say again you're coming in weak." N292SP replied, "yeah we're picking up some prop ice ah can you get us lower." At 0945:51, the controller instructed N292SP, "...descend and maintain three thousand seven hundred." N292Sp replied, "three thousand seven hundred we're at three thousand five hundred two four zero." N292SP replied, " two four zero and can we expect lower we're getting a load of ice up here."
After several transmissions between the controller and N292Sp confirming the assigned heading, Elmira approach provided the Ithaca weather to N292SP at 0947:34, "...estimated ceiling five hundred broken seven hundred overcast visibility four fog wind three four zero at one one Ithaca altimeter two niner eight niner." N292SP replied, "two niner eight niner and ah can we expect to get lower soon." the controller said, "two sierra papa maintain three thousand six hundred that's as low as I can go right now you can expect lower in three miles." At 0948:00 N292SP transmitted, "roger we're having a hard time holding on to three three." The controller responded, " you need to maintain a mul...the ah the altitudes I give you can't just arbitrarily go lower."
0948:33: N292SP transmitted, "two sierra papa ah any way chance of lower." Three seconds later N292SP stated, " two sierra papa I need help." At 0948:42, the controller transmitted, " two sierra papa maintain three thousand one hundred." After an unintelligible transmission from N292SP, the controller transmitted, "three sierra papa descend and maintain two thousand three hundred this is an emergency vectoring altitude two thousand three hundred." N292SP responded, "two thousand three hundred here we go." N292SP then transmitted, "say again the heading you want us on." The controller replied, "fly heading two four zero." N292SP acknowledged the heading and at 0949:15, the controller advised, " november two sierra papa radar contact lost."
N292SP advised, "okay we're establishing ourselves on the two four zero and we're gonna [sic] make that altitude I think." At 0949:43, N292SP inquired, "say again the altitude for two four zero." N292SP inquired, "say again the altitude for two four zero." N292SP advised, "two thousand three hundred we have an awful lot of ice we barely maintain." The controller responded, "two sierra papa roger that's an emergency vectoring altitude that's as ah low as I can go in that area at this time." At 0951:34, the controller transmitted, " piper two sierra papa how's the icing." There were no further communications with the airplane.
One of the surviving passengers, Kerrie rogers, stated; "...I believe it was sometime around 9:40AM we were in the Cortland area and the windshield was icing up. We couldn't land at the Cortland Airport because of the fog and we couldn't see the ground. We were all wearing earphones so we could hear the transmissions...For about the last three to five minutes of the flight Mr. Freeman took over the flying. The windshield was icing up bad and the plane was also taking on ice and getting shaky..."
Another surviving passenger, Matthew Massaro, stated; "...During the trip we were listening to the conversations of the pilot for the fun of it...The copilot called on the radio and asked permission to go to a lower elevation because of an icing condition. I looked out the windshield and all I could see was ice. I believe that the pilot was getting freaked by the weather condition. Mr. Freeman asked if she wanted him to take over and she said yes. I think he took over at that time. It was only a minute before the plane went down. Just before we hit the plane was like jerking and dropping a little. The engine did not sound like it was having a problem. Mr. Freeman was calm while talking on the radio and there was no warning that we were in trouble."
The accident occurred during the hours of daylight at approximately 42 degrees...
