Narrative:

It was about XA00 inbound to avl from gmu when we were descended to 5000 ft and cleared for the avl ILS runway 34 approach. Although I was the designated PIC on paper, my co-captain was flying his leg from the left seat. Avl had some rather dense fog earlier but at the time of our arrival it had cleared fairly rapidly and we had good visibility. Since we are only provided with 1 set of charts in the plane, my co-captain had the plate on his side, causing me to lean over a bit to see the chart. What had happened was that once we were cleared for the approach, we descended to the FAF altitude of 3700 ft instead of the GS intercept altitude of 4400 ft. On the profile of the printed chart the FAF altitude was in bold print and I overlooked the finer print of the GS intercept altitude. Lesson learned: do a better job briefing the approach.

Title: HAWKER 800 CREW DSNDED BELOW GS INTERCEPT ALT ON THE AVL RWY 34 APCH.

Narrative: IT WAS ABOUT XA00 INBOUND TO AVL FROM GMU WHEN WE WERE DSNDED TO 5000 FT AND CLRED FOR THE AVL ILS RWY 34 APCH. ALTHOUGH I WAS THE DESIGNATED PIC ON PAPER, MY CO-CAPT WAS FLYING HIS LEG FROM THE L SEAT. AVL HAD SOME RATHER DENSE FOG EARLIER BUT AT THE TIME OF OUR ARR IT HAD CLRED FAIRLY RAPIDLY AND WE HAD GOOD VISIBILITY. SINCE WE ARE ONLY PROVIDED WITH 1 SET OF CHARTS IN THE PLANE, MY CO-CAPT HAD THE PLATE ON HIS SIDE, CAUSING ME TO LEAN OVER A BIT TO SEE THE CHART. WHAT HAD HAPPENED WAS THAT ONCE WE WERE CLRED FOR THE APCH, WE DSNDED TO THE FAF ALT OF 3700 FT INSTEAD OF THE GS INTERCEPT ALT OF 4400 FT. ON THE PROFILE OF THE PRINTED CHART THE FAF ALT WAS IN BOLD PRINT AND I OVERLOOKED THE FINER PRINT OF THE GS INTERCEPT ALT. LESSON LEARNED: DO A BETTER JOB BRIEFING THE APCH.
