Narrative:

I was flying 'under the hood' on an ILS approach for runway 26 at ftg. The safety pilot, who meets the insurance minimums for the rental aircraft, had assumed the position as PIC. I was flying on an inbound course 8.9 DME from runway 26 and on a 265 degree radial from byers VOR. The visibility was greater than 10 SM and the ceiling was greater than 10000 ft. The safety pilot and I know the area well and idented all navaids along our route from goodland, ks. The safety pilot continued to give me radar vectors to ftg. I began to query the safety pilot asking if he could see ftg at 16 DME from denver VOR. At this time I noticed that our navaids were not operating properly. I queried the safety pilot once more, 'do you see the airport?' he gave me no indication of being off course. When he again replied no, I decided to come out from under the hood. When I looked up and outside, I was aware that we had inadvertently entered the TCA of class B at denver international airport. I informed the safety pilot that we were inside the TCA. At that time the safety pilot took over the controls and informed me that he was now PIC. I relinquished all controls and began scanning the area for traffic. The PIC immediately proceeded to descend and turn left to an easterly heading. We landed at ftg within 5 mins. The 3 contributing factors that led to this incident are: 1) the miscom between the safety pilot and I en route. 2) the safety pilot misidenting visual references and being unsure of our position after byers VOR, which threw us off course. 3) and finally, the poorly maintained avionics of the rental aircraft that gave us poor reception of the ILS and denver VOR. Furthermore, the ADF became inoperative and was unusable.

Title: COMMERCIAL PLT INST TRAINEE UNDER IFR HOOD IN VMC ON VECTORS FROM PIC SAFETY PLT ENTERS DEN CLASS B AIRSPACE.

Narrative: I WAS FLYING 'UNDER THE HOOD' ON AN ILS APCH FOR RWY 26 AT FTG. THE SAFETY PLT, WHO MEETS THE INSURANCE MINIMUMS FOR THE RENTAL ACFT, HAD ASSUMED THE POS AS PIC. I WAS FLYING ON AN INBOUND COURSE 8.9 DME FROM RWY 26 AND ON A 265 DEG RADIAL FROM BYERS VOR. THE VISIBILITY WAS GREATER THAN 10 SM AND THE CEILING WAS GREATER THAN 10000 FT. THE SAFETY PLT AND I KNOW THE AREA WELL AND IDENTED ALL NAVAIDS ALONG OUR RTE FROM GOODLAND, KS. THE SAFETY PLT CONTINUED TO GIVE ME RADAR VECTORS TO FTG. I BEGAN TO QUERY THE SAFETY PLT ASKING IF HE COULD SEE FTG AT 16 DME FROM DENVER VOR. AT THIS TIME I NOTICED THAT OUR NAVAIDS WERE NOT OPERATING PROPERLY. I QUERIED THE SAFETY PLT ONCE MORE, 'DO YOU SEE THE ARPT?' HE GAVE ME NO INDICATION OF BEING OFF COURSE. WHEN HE AGAIN REPLIED NO, I DECIDED TO COME OUT FROM UNDER THE HOOD. WHEN I LOOKED UP AND OUTSIDE, I WAS AWARE THAT WE HAD INADVERTENTLY ENTERED THE TCA OF CLASS B AT DENVER INTL ARPT. I INFORMED THE SAFETY PLT THAT WE WERE INSIDE THE TCA. AT THAT TIME THE SAFETY PLT TOOK OVER THE CTLS AND INFORMED ME THAT HE WAS NOW PIC. I RELINQUISHED ALL CTLS AND BEGAN SCANNING THE AREA FOR TFC. THE PIC IMMEDIATELY PROCEEDED TO DSND AND TURN L TO AN EASTERLY HDG. WE LANDED AT FTG WITHIN 5 MINS. THE 3 CONTRIBUTING FACTORS THAT LED TO THIS INCIDENT ARE: 1) THE MISCOM BTWN THE SAFETY PLT AND I ENRTE. 2) THE SAFETY PLT MISIDENTING VISUAL REFS AND BEING UNSURE OF OUR POS AFTER BYERS VOR, WHICH THREW US OFF COURSE. 3) AND FINALLY, THE POORLY MAINTAINED AVIONICS OF THE RENTAL ACFT THAT GAVE US POOR RECEPTION OF THE ILS AND DENVER VOR. FURTHERMORE, THE ADF BECAME INOP AND WAS UNUSABLE.
