Narrative:

While training a 1400 hour (over 20 yrs) pilot who had bought an eclipse 500 vlj and was awaiting his type rating training; we flew IFR to hnd; and then canceled IFR in order to do some VFR air work and lndgs in the jet. Although the client/'student' had done quite well the previous 4 days; he was not having a good day on this flight and required constant attention; as he was well behind the aircraft. On one of his landing approachs he was very wide abeam; had poor to no airspeed control and wouldn't bank over approximately 10 degrees; from base leg to final; despite my repeated calls for him to increase bank and tighten the turn. As a result; we may have drifted over the road that marks the southern boundary of the las class B airspace; which goes down to the surface at that point - our altitude was approximately 500 ft AGL. Just after my last call for him to tighten the turn and monitor his airspeed; the stall warning came on as he increased bank and added too much back pressure. I took over the controls and landed after telling him not to fight me; as I could feel and see his hand on the side stick. Even though I had demonstrated a VFR pattern to a low approach prior to his landing attempts; I think it would have been better to either let him fly a straight-in approach to a full stop; or just 'demonstration' the full stop landing myself. He had flown and landed well the previous 4 days; but this wasn't his day and I was too slow to recognize how far behind the aircraft he was. It won't happen again.

Title: ECLIPSE 500 STUDENT PILOT ENTERED THE CLASS B AIRSPACE OF ADJACENT ARPT WHILE FLYING A VFR TFC PATTERN.

Narrative: WHILE TRAINING A 1400 HR (OVER 20 YRS) PLT WHO HAD BOUGHT AN ECLIPSE 500 VLJ AND WAS AWAITING HIS TYPE RATING TRAINING; WE FLEW IFR TO HND; AND THEN CANCELED IFR IN ORDER TO DO SOME VFR AIR WORK AND LNDGS IN THE JET. ALTHOUGH THE CLIENT/'STUDENT' HAD DONE QUITE WELL THE PREVIOUS 4 DAYS; HE WAS NOT HAVING A GOOD DAY ON THIS FLT AND REQUIRED CONSTANT ATTN; AS HE WAS WELL BEHIND THE ACFT. ON ONE OF HIS LNDG APCHS HE WAS VERY WIDE ABEAM; HAD POOR TO NO AIRSPD CTL AND WOULDN'T BANK OVER APPROX 10 DEGS; FROM BASE LEG TO FINAL; DESPITE MY REPEATED CALLS FOR HIM TO INCREASE BANK AND TIGHTEN THE TURN. AS A RESULT; WE MAY HAVE DRIFTED OVER THE ROAD THAT MARKS THE SOUTHERN BOUNDARY OF THE LAS CLASS B AIRSPACE; WHICH GOES DOWN TO THE SURFACE AT THAT POINT - OUR ALT WAS APPROX 500 FT AGL. JUST AFTER MY LAST CALL FOR HIM TO TIGHTEN THE TURN AND MONITOR HIS AIRSPD; THE STALL WARNING CAME ON AS HE INCREASED BANK AND ADDED TOO MUCH BACK PRESSURE. I TOOK OVER THE CTLS AND LANDED AFTER TELLING HIM NOT TO FIGHT ME; AS I COULD FEEL AND SEE HIS HAND ON THE SIDE STICK. EVEN THOUGH I HAD DEMONSTRATED A VFR PATTERN TO A LOW APCH PRIOR TO HIS LNDG ATTEMPTS; I THINK IT WOULD HAVE BEEN BETTER TO EITHER LET HIM FLY A STRAIGHT-IN APCH TO A FULL STOP; OR JUST 'DEMO' THE FULL STOP LNDG MYSELF. HE HAD FLOWN AND LANDED WELL THE PREVIOUS 4 DAYS; BUT THIS WASN'T HIS DAY AND I WAS TOO SLOW TO RECOGNIZE HOW FAR BEHIND THE ACFT HE WAS. IT WON'T HAPPEN AGAIN.
